Common reasons people leave
Why People Switch From Formstack
There is no free plan, and the first plan is $83 to $99 a month for one user
What it costs you: Formstack gives you 14 days, then $83 a month billed annually or $99 month-to-month for one builder user, 25 forms, 1,000 submissions per form and 2 GB. Capterra reviewers call the licenses "fairly expensive". FormNX starts free with unlimited forms and submissions, and Pro costs less than a fifth of that.
Submissions are capped per form, and the overflow never reaches your dashboard
What it costs you: The Forms plan stores 1,000 submissions per form, Suite stores 5,000, and only custom-priced Enterprise is unlimited. Formstack's help center says submissions over the limit are emailed to you instead of stored, so they never reach your table, reports or exports. FormNX never counts submissions, on any plan.
Signatures with an audit trail and generated documents are separate products
What it costs you: The Forms signature field saves a picture. Formstack's own page says: "Need an audit trail? Check out Formstack Sign!", a separate product with no listed price, and Documents is another. Suite bundles them at $250 to $299 a month. FormNX gives every plan a signature field with a full audit trail, and Pro adds the PDF builder.
Seats, approvals, partial submissions, HIPAA and the API are all extras
What it costs you: One builder seat comes with Forms; extras are a quote. Approvals need the Workflows Pro add-on, partial submissions the Conversion Kit plugin, HIPAA a paid add-on, and the API an add-on or Enterprise. None of those prices are published. Every FormNX Pro plan includes 5 users per workspace, partial submissions, webhooks and every native integration.
Reviewers describe contracts that are hard to leave and support that is slow to answer
What it costs you: Trustpilot reviewers say cancelling is "next to impossible" with "no cancel button", and that support is "non-existent". Capterra reviewers mention "slow replies". FormNX reviewers on G2 praise the support team: replies often within minutes, and product changes made on request.
The newer form features are not there at any tier
What it costs you: No native quiz mode, so grading is a formula recipe. No countdown timer, voice field, camera capture or age verification. One language per form. No email OTP, and throwaway emails get through. FormNX has all of it: quiz mode, voice, camera and password protection free; timer, OTP, temp-mail blocking and partial submissions on Pro.
"FormNX offers an incredibly intuitive interface that makes form creation seamless and efficient. Its vast array of customization options allows for the creation of forms that perfectly align with my brand's aesthetic. Above all, what sets FormNX apart is its customer support team."
FormNX's approach
Where FormNX Differs From Formstack
Formstack prices by seat, by form and by submission, and sells signatures and documents separately. Six quick comparisons show what that costs, and what FormNX does instead.
What It Costs to Publish Your First Form
A 14-day trial, then $83 to $99 a month for one user.
No free plan. The Forms plan is $83 a month billed annually or $99 month-to-month, for one builder user, 25 forms, 1,000 submissions per form and 2 GB. Approvals, document generation and audit-trailed signatures need Suite at $250 to $299 a month or an add-on with no listed price. Capterra reviewers' top complaint is the price: "the licenses are fairly expensive".
Free forever, with unlimited forms and submissions.
No expiry date, no card on file. Free includes unlimited forms and submissions, an e-signature field, quiz mode, the AI form builder, Stripe payments and voice and camera fields. Pro, from around $15 a month, removes branding and adds the PDF builder, four gateways, every integration and 5 users per workspace. Less than a fifth of Formstack's entry price, for a whole team.
What Happens When a Form Gets Busy
1,000 submissions per form on Forms, 5,000 on Suite.
Ever had a form fill up faster than you planned? On Formstack that is an expensive day. Every plan below custom-priced Enterprise caps submissions per form. Formstack's help center says anything over the cap is emailed to you instead of stored, so it is missing from your submissions table, reports and exports until you buy more capacity.
Unlimited submissions on every plan, including free.
No per-form counter. Ten responses in March, ten thousand in April: every one is stored, shows in your dashboard and charts, and fires its notifications and integrations on arrival. Want a cap? Set your own response limit, schedule open and close dates, or let people save a draft.
How Many People Can Build Forms
One builder user on Forms, three on Suite, and a quote for every extra.
How many people on your team need to edit a form? With Formstack, that question has a price. Forms includes one builder seat and Suite includes three. The pricing page says you can "add more users" but never says what a seat costs, and unlimited users appear only on custom-quoted Enterprise.
5 users per workspace on every Pro plan.
From Pro Plan 1, each workspace seats 5 users with Admin, Member and Viewer roles. Pro plans scale from 1 to 5 workspaces so each department keeps its own forms apart; Agency plans run 50 or unlimited workspaces for client work. The seat price is printed on the pricing page and does not move when your team grows.
Signatures, Documents and the Products You Have to Add
Three products: Forms, Documents and Sign.
The Forms signature field saves an image with the submission. Its own page adds: "Need an audit trail? Check out Formstack Sign!", a separate product with no price on the site. Filled documents are Formstack Documents, another separate product that meters deliveries. Suite bundles all three for $250 to $299 a month with 250 deliveries included. Branding removal, at least, comes with every paid plan.
Signatures free, documents designed in the same app.
The e-signature field is on every plan, including free: draw or type, with a full audit trail. On paid plans the drag-and-drop PDF builder lays out the document with your logo, images, page breaks and merge tags, from 100+ templates or an AI layout. Signatures embed into the PDF, finished files attach to notification emails, and bulk export delivers hundreds as one ZIP. Branding removal comes with Pro.
Add-Ons, Plugins and the Zapier Account in the Middle
Approvals, partial submissions, HIPAA and the API are all extra.
This is where the bill keeps growing after you sign up. On Forms, approval routing needs the Workflows Pro add-on, partial submissions the paid Conversion Kit plugin, HIPAA a "+ Add On", and the API an add-on or Enterprise plan. None of those prices are published. The directory lists 250+ apps, with native Google Sheets, HubSpot, Salesforce and Mailchimp, but Slack and Discord are built by Zapier, so they need a Zapier account too.
One Pro plan includes the lot.
Pro includes partial submissions, a webhook to any URL, and native Google Sheets, Slack, Discord, Mailchimp and Telegram, with no middleman account. The same webhook connects more than 1,000 other apps through Zapier, Pabbly and Make. See all integrations.
The Features That Are Not There at Any Tier
No quiz mode, timer, camera, voice or email OTP.
To be fair, Formstack covers the classics: conditional logic, calculating fields, Save & Resume, prefill, campaign tracking and a Lightbox popup. The newer fields are another story. No native quiz mode (grading is a four-step formula recipe), no countdown timer, no voice field, no camera capture, no native age verification, one language per form, no email OTP, and throwaway email addresses go straight through.
Quiz mode, voice, camera and popups on the free plan.
Quiz mode, a voice recorder, camera capture, popup forms and password protection are free. Email OTP, disposable-email blocking, the form timer and partial submissions come with Pro. Age verification checks min, max and age as of a cutoff date, and forms publish in 40+ languages, right-to-left included, with a switcher inside the form.
"There are super features in this form creator. They REALLY took a lot of time to create a fantastic program. I was using another form creator but switching a lot of my forms to this application. The tech support is amazing."
Feature by feature
FormNX vs Formstack: Detailed Comparison
Pricing, Limits and the Real Cost
Formstack has four tiers and no free plan. Forms is $83 a month billed annually or $99 month-to-month: one builder user, 25 forms, 1,000 submissions per form, 2 GB. Suite bundles Forms, Documents and Sign for $250 or $299 a month: three users, 100 forms, 5,000 submissions per form, 10 GB, 250 document deliveries a month and unlimited eSignatures. Salesforce Solutions and Enterprise are custom-quoted, and only Enterprise has unlimited users and submissions.
So what does it really cost? That depends on the extras: approval routing on Forms is the Workflows Pro add-on, partial submissions the Conversion Kit plugin, HIPAA an add-on on Forms and Suite, and extra seats a quote. None of those prices appear on the pricing page.
With FormNX there is no ladder. Free has unlimited forms and submissions, e-signature and quiz mode. Pro, from around $15 a month, removes branding and adds 5 users per workspace, four payment gateways, the PDF builder, email OTP, the form timer, partial submissions and every integration. Agency, from about $49 a month, covers 50 to unlimited client workspaces. A busy month costs the same as a quiet one. Against Formstack Forms, FormNX Pro costs a fraction, seats five times the users and has no submission cap.
Why Most Teams Pick FormNX Over Formstack
Formstack keeps Salesforce-native forms, HIPAA and single sign-on on custom-quoted tiers and add-ons, and meters seats, forms and submissions everywhere below Enterprise.
Most people looking for a Formstack alternative want something simpler: forms that take payments, collect signatures and produce documents, for a whole team, without a sales call for every extra. That is the work FormNX does better, for less.
- A free plan that never expires, instead of a 14-day trial and $83 to $99 a month.
- No submission cap on any plan, so nothing is emailed to you instead of stored.
- 5 users per workspace on every Pro plan, instead of one seat and a quote for extras.
- E-signature with a full audit trail on the free plan, instead of a separate signing product.
- A PDF builder inside the form tool, with bulk ZIP export, instead of a metered documents product.
- Partial submissions, webhooks and native Slack in Pro, instead of a paid plugin, an API add-on and a Zapier account.
- Fields Formstack does not have: quiz mode, a form timer, email OTP, voice, camera and age verification.
Building, Logic and Fields: FormNX Goes Further
Both cover the essentials: a drag-and-drop builder, an AI generator, conditional logic, calculations, multi-page forms, file uploads, prefill, Save & Resume and a popup embed. On Formstack those start at $83 a month; on FormNX most are free. Past the essentials, FormNX goes further.
- Quiz mode is built in. Scores, grades and answer feedback on the free plan. In Formstack you build scoring from point values and a calculating field.
- Fields Formstack does not have. A voice recorder, camera capture and native age verification that can check age as of a cutoff date.
- Forms in 40+ languages. One form, 40+ languages with a switcher inside it, right-to-left included. Formstack sets one of 36 interface languages per form.
- An official WordPress plugin. Paste a form link into the FormNX block, shortcode or Elementor widget, no embed code needed, and open it inline or as a popup on click, delay, scroll or exit intent. It works on the free plan (setup guide). Any other site, a share link and an authorized-URL whitelist on paid plans are covered too.
- Validation from a list. Email, URL, phone, numeric, letters-only, length limits and contains rules, with no formula to write.
- Smarter contact fields. Address with Google Autocomplete, and phone with a country-code selector that checks the format.
- Answers you can reuse. Type @ to recall an earlier answer, prefill from the URL, capture UTM parameters. Formstack has no native answer piping.
- Templates by the thousand. 1,000+ form templates and 100+ PDF templates, against a Formstack library its own blog sizes at more than 280.
The full field list covers every field type.
Spam, Security and Data Quality: FormNX Checks Who Is Submitting
Formstack relies on an invisible reCAPTCHA and a Unique Fields setting that rejects a repeated value. It never asks a public respondent to prove their email is real, temp-mail domains go straight through, and its stronger controls sit in a paid Enhanced Data Security add-on.
FormNX treats data quality as part of the form:
- Four anti-spam layers built in. One-toggle CAPTCHA, an invisible honeypot, per-IP rate limiting and a live disposable-email blocklist.
- Email OTP on any public form. On Pro, so every address in your list belongs to someone who opened it.
- Password protection and duplicate checks on the free plan, including one submission per IP.
- Privacy by default. GDPR-compliant handling, consent fields, EU data hosting, TLS in transit, no tracking cookies on published forms.
Product Catalog & Shopping Cart
Formstack builds order forms from parts: priced options on choice fields, number fields for quantity, a calculating field for the total, discount codes, and PayPal, Stripe or Authorize.Net with no Formstack fee. You assemble and maintain each piece, on a plan from $83 a month.
FormNX has a Products field that puts a real catalog inside the form: a title, price, descriptions and up to five photos per product, options like Size or Color with their own price and out-of-stock switch, and a cart customers fill from product cards.
The cart totals itself. Tax (on top or included), shipping with a free-shipping threshold, and discount codes with usage limits and expiry dates apply automatically. The total is paid through Stripe, PayPal, Razorpay or Square with a 0% FormNX platform fee on paid plans. See the order form builder. On all Pro plans.
Why FormNX Is the Better Formstack Alternative
FormNX is for people who like what Formstack does but are tired of paying enterprise prices for a single seat. Unlimited forms and submissions on every plan, e-signature with a full audit trail for free, and a Pro plan at a fraction of Formstack's entry price that seats 5 users per workspace and adds four gateways, the PDF builder, partial submissions and 1,000+ app integrations, native or through Zapier, Make and Pabbly. On top: quiz mode, email OTP, a form timer, voice, camera and 40+ languages.

Which is right for you?
An Honest Recommendation
Choose FormNX if…
- You want a free plan with unlimited forms and unlimited submissions, instead of a 14-day trial and an $83 to $99 a month first plan
- You never want a submission emailed to you because a form passed its cap
- You need e-signatures with an audit trail on every plan, without buying a separate signing product
- You want branded PDFs designed in a drag-and-drop builder inside the form tool, with bulk ZIP export, rather than a separate metered documents product
- Your whole team builds forms: 5 users per workspace from the first Pro plan, instead of one seat and extra seats priced on request
- You want partial submissions, webhooks and native Slack and Google Sheets included in Pro, with no add-on or Zapier account
- You run quizzes, tests or timed assessments and want scoring and a countdown built in
- You need email OTP verification, disposable-email blocking, camera capture, voice answers or forms in 40+ languages
Choose Formstack if…
- Your forms must be Salesforce-native, and your budget covers its custom-quoted Salesforce Solutions tier
- You need HIPAA with a signed BAA today and can pay the Forms or Suite price plus the HIPAA add-on, which has no listed price
- Your process already runs on Formstack Documents merges and Formstack Sign envelopes, and you would rather keep paying $250 to $299 a month for Suite than rebuild
- You need SSO, SCIM and a dedicated customer success manager, which sit on its custom-priced Enterprise plan
Switching is straightforward
How to Migrate From Formstack
Export your submissions from Formstack
Open each form's Submissions tab and export to CSV or Excel. Download any uploaded files you still need, since your Formstack storage closes with the account. Keep the form open as a reference for fields, calculations and conditional logic while you rebuild.
Rebuild the form in FormNX
Use the drag-and-drop builder, describe the form to the AI builder in plain English, or start from one of 1,000+ templates. Things that were add-ons or separate products in Formstack - audit-trailed signatures, PDF documents, partial submissions - are settings here. Or send us the public link to your form and our team rebuilds it for you, free.
Swap the embed and close the old form
Replace the Formstack JavaScript or iFrame embed on your website with the FormNX embed, or share the new form link in place of the old one. Leave the Formstack form open until you have seen submissions arriving in FormNX, then close it before your next renewal date.

FormNX vs Formstack: FAQs
-
Is there a free version of Formstack?
Is Formstack free? No. Formstack has no free plan. It offers a 14-day free trial of its Forms product with no credit card required, and after that you choose a paid plan. The cheapest is Forms at $83 a month billed annually or $99 month-to-month, for one builder user, 25 forms, 1,000 submissions per form and 2 GB of storage. FormNX has a free plan that never expires, with unlimited forms and unlimited submissions, an e-signature field, scored quiz mode and an AI form builder.
-
Can you use Formstack for free?
Only for the 14 days of the trial. When it ends, your forms stop working until you pay for a plan, and the cheapest one is Forms at $83 to $99 a month. If you want to keep collecting responses without paying, FormNX is a free Formstack alternative with unlimited submissions, e-signature, quiz mode and Stripe payments on its free plan, and no time limit.
-
How much does Formstack cost?
Formstack pricing has four tiers. Forms is $83 a month billed annually or $99 month-to-month, with 1 builder user, 25 forms, 1,000 submissions per form and 2 GB of storage. Suite bundles Forms, Documents and Sign for $250 or $299 a month, with 3 builder users, 100 forms, 5,000 submissions per form, 10 GB, 250 document deliveries a month and unlimited eSignatures. Salesforce Solutions and Enterprise are custom-quoted; Enterprise is the only tier with unlimited users and submissions. HIPAA is an add-on on Forms and Suite, and extra seats, the Workflows Pro add-on and the Conversion Kit plugin are priced on request. Check formstack.com/pricing for current numbers.
-
What happens when you go over the Formstack submission limit?
According to Formstack's help center, submissions that arrive after you pass your limit are not lost, but they are emailed to you instead of being stored in the Formstack database. That means they do not appear in your submissions table, reports or exports until you buy more capacity. The Forms plan stores 1,000 submissions per form and Suite stores 5,000; only Enterprise is unlimited. Storage works the same way: when it runs out, the file-upload fields on your forms are deactivated. FormNX has no submission cap on any plan, so every response lands in your dashboard.
-
What is the new name of Formstack?
The company behind Formstack renamed itself Intellistack and moved its headquarters from Fishers, Indiana to Denver, Colorado. The products still sell under the Formstack name - Formstack Forms, Documents and Sign - alongside Formsite, which the same company owns, and a new AI process platform called Intellistack Streamline. Pricing, plan limits and the 14-day trial did not change with the rebrand, which is why many teams still compare Formstack alternatives such as FormNX.
-
What is Formstack used for?
Formstack is used to build online forms, generate documents from the answers and collect electronic signatures, mostly by mid-sized and enterprise teams, many of them on Salesforce. Its typical jobs are intake forms, registrations, order and payment forms, approval workflows and HIPAA-covered healthcare forms. FormNX covers the same jobs - forms, payments, PDFs and signatures - and adds quiz mode, a form timer, email OTP verification, a product catalog and a free plan with unlimited submissions.

Which is better, Formstack or Google Forms?
In a Formstack vs Google Forms comparison, most people are better off with neither. Google Forms is free and unlimited but has no payments, e-signature, PDF generation or branding removal. Formstack has all of those, but no free plan, and starts at $83 to $99 a month for one user with 1,000 submissions per form. FormNX combines the two: unlimited submissions on a free plan, like Google Forms, plus e-signature, quiz mode and Stripe payments on that free plan, and the PDF builder, four payment gateways and every integration from around $15 a month. See our Google Forms alternative page.

Which is better, Formstack or Jotform?
Whether you search Formstack vs Jotform or Jotform vs Formstack, the answer is the same: Jotform is cheaper to start and has more than 20,000 templates, while Formstack leans on Salesforce integration and enterprise compliance. Both meter your usage. Formstack caps submissions at 1,000 or 5,000 per form on its paid plans and has no free plan. Jotform caps monthly submissions by tier - 100 on Free, 1,000 on Bronze, 2,500 on Silver and 10,000 on Gold - and caps active forms too, at 5, 25, 50 and 100. FormNX has no caps at all, with unlimited forms and submissions on every plan. See our Jotform alternative comparison for the full breakdown.

What are the best alternatives to Formstack?
The Formstack alternatives and Formstack competitors that come up most are FormNX, Jotform, Cognito Forms, Fillout, Tally, Zoho Forms, Typeform and Google Forms. FormNX is the pick if you want to stop paying per seat and per submission: it is free with unlimited forms and submissions, and Pro seats 5 users per workspace from around $15 a month. Jotform has the biggest template library but caps forms and submissions by tier. Cognito Forms is strong on calculations but caps entries at 100 a month on its free plan.

-
What is the best free alternative to Formstack?
Searching for a Formstack alternative, free of charge? FormNX is the best free Formstack alternative if you need more than a bare form. Its free plan includes unlimited forms and unlimited submissions, an e-signature field with an audit trail, scored quiz mode, Stripe payments, an AI form builder, a voice-recording field, camera capture, password protection and duplicate-submission prevention, with no card and no expiry. Formstack has no free plan at all. Other free Formstack alternatives people compare are Google Forms, which has no payments or e-signature, Tally, which stops at the form, and Jotform, whose free plan is capped at 5 forms and 100 submissions a month.
-
What is the best free form builder?
FormNX, if you measure by what the free plan includes. It has unlimited forms and unlimited submissions, an e-signature field, scored quiz mode, calculation fields, Stripe payments, an AI form builder, a voice-recording field, camera capture, password protection and duplicate prevention, with no credit card and no time limit. Google Forms is also free and unlimited but has no payments, signatures or PDFs. Formstack has no free version, and Jotform and Cognito Forms stop their free plans at 100 submissions or entries a month. See the FormNX free plan for the full list.
-
What is the best form building software?
The best form builder is the one that covers your whole job without a plan upgrade for every feature. FormNX combines forms, payments through Stripe, PayPal, Razorpay and Square, e-signatures with an audit trail, a drag-and-drop PDF builder, quiz mode, a product catalog and native integrations, with unlimited submissions on every plan and 5 users per workspace on Pro from around $15 a month. Formstack covers forms, documents and signatures too, but as three products, with an $83 to $99 a month entry price for one user and per-form submission caps. Jotform and Cognito Forms are the other names on most shortlists, and both cap submissions by tier.
-
Is Formstack HIPAA compliant?
Formstack offers HIPAA compliance, but on the Forms and Suite plans it is a paid add-on with an unpublished price. It is included only on the custom-quoted Salesforce Solutions and Enterprise tiers, with a standard business associate agreement. FormNX is built around GDPR-compliant data handling, with consent fields, EU data hosting, TLS in transit, password-protected forms and no tracking cookies on your published forms. If HIPAA with a signed BAA is a legal requirement for your forms today, Formstack's add-on covers it; for every other form, FormNX collects the same data without the add-on ladder.
-
Does Formstack have e-signatures?
Formstack Forms has a signature field where respondents type or draw a signature, which is saved as an image with the submission. Formstack's own feature page says "Need an audit trail? Check out Formstack Sign!", a separate product with no listed price. Unlimited eSignatures with an audit trail are bundled only in the Suite plan at $250 to $299 a month. FormNX puts an e-signature field with an audit trail on every plan, including free. Respondents can type, draw or upload a signature, and on paid plans it embeds straight into the branded PDFs your form produces.
-
Does Formstack integrate with Google Sheets and Slack?
Yes to Google Sheets, and only through Zapier for Slack. The Formstack integrations directory lists more than 250 apps, and Google Sheets is a native connection on its paid plans. Its Slack integration is not native: Formstack's own Slack page says the integration is built by Zapier, so you also need a Zapier account, and the same is true for Discord. API access is an add-on or an Enterprise feature. FormNX has native Google Sheets, Slack, Discord, Mailchimp and webhook connections on paid plans, and its webhooks reach 1,000+ more apps through Zapier, Pabbly and Make.
-
Can you make a quiz in Formstack?
Yes, but you build the scoring yourself. Formstack's own guide creates a graded quiz in four steps: assign a point value to each list option, add a read-only number field, set it to self-calculate the total, and show the result. There is no answer feedback, no question bank and no countdown timer. FormNX has a native quiz mode on the free plan with scoring, grading, answer feedback and admin insights. Random question subsets and a form timer that auto-submits at zero are available on paid plans.
-
Is Formstack part of Salesforce?
No. Formstack is not owned by Salesforce. It is a product of Intellistack, the renamed Formstack company, and it sells a separate Salesforce-native product, Formstack for Salesforce, through the AppExchange on its custom-quoted Salesforce Solutions tier. If your forms do not need to live inside Salesforce, that tier is money you do not need to spend. FormNX sends every submission to any CRM through webhooks, which also reach Zapier, Pabbly and Make, on its paid plans, with no custom quote.
-
Is Formstack the same as Microsoft Forms?
No. Microsoft Forms is the free survey and quiz tool inside Microsoft 365, with no payments, e-signatures, document generation or branding control. Formstack is a paid, enterprise-priced form, document and signature suite that starts at $83 to $99 a month. FormNX sits between them: free with unlimited submissions like Microsoft Forms, plus payments, e-signature, a PDF builder and quiz mode. See our Microsoft Forms alternative page.
-
Does Formstack have an API and webhooks?
Webhooks are available on every paid Formstack plan. Access to the Formstack API needs an add-on or an Enterprise-level plan, and daily API rate limits vary by plan, so a developer integration is one more cost on top of the Forms plan. FormNX includes a webhook that posts every submission to any URL on its paid plans from around $15 a month, alongside native Google Sheets, Slack, Discord and Mailchimp connections.
-
Which is better, Formstack or Typeform?
In a Formstack vs Typeform comparison, they solve different jobs. Typeform is built for one-question-at-a-time conversational surveys and caps responses by plan. Formstack is built for enterprise intake, documents and approvals, and caps submissions per form with no free plan. FormNX does both: multi-step or single-question layouts with a progress bar, unlimited submissions on every plan, and payments, e-signature and PDFs built in. See our Typeform alternative comparison for the full breakdown.
-
Is Formstack secure?
Formstack lists data encryption, invisible reCAPTCHA, GDPR tools and Section 508 accessible forms on its feature pages. Its stronger controls cost extra: HIPAA is an add-on on Forms and Suite, an Enhanced Data Security add-on is sold separately, and SSO and SCIM sit on the custom-quoted Enterprise plan. FormNX handles data with GDPR-compliant consent fields, EU data hosting and TLS in transit, and puts password protection, CAPTCHA and duplicate checks on the free plan, with email OTP verification and authorized embed URLs on Pro.
-
What do Formstack reviews say?
Formstack reviews on Capterra credit the drag-and-drop builder, the conditional logic and the integration breadth, and complain most about price: "the licenses are fairly expensive", "not for small budgets", "many advanced features are locked behind top-tier plans". Trustpilot reviewers focus on billing and support, describing cancellation as "next to impossible" and support as "non-existent". FormNX reviewers on G2 and Trustpilot single out its support team and its feature set, and the FormNX quotes on this page link to their verified reviews.
-
Is FormNX better than Formstack?
For most teams replacing Formstack, yes. FormNX is free with unlimited forms and submissions, where Formstack has no free plan and stores 1,000 or 5,000 submissions per form. FormNX Pro, from around $15 a month, seats 5 users per workspace and includes the PDF builder, partial submissions, four payment gateways and native Slack and Google Sheets; on Formstack those are extra seats, separate products, a paid plugin and a Zapier account, all on top of the Forms plan price. E-signature with an audit trail is free on FormNX and a separate product on Formstack. FormNX also adds quiz mode, a form timer, email OTP verification, voice answers, camera capture and forms in 40+ languages, none of which Formstack has at any tier.
-
How do I migrate from Formstack to FormNX?
To migrate from Formstack, export each form's submissions from the Submissions tab as CSV or Excel and download any uploaded files you need. Rebuild the form in FormNX with the drag-and-drop builder, the AI builder or one of 1,000+ templates. Then replace the Formstack embed code on your site, or the link you share, with the FormNX version, and close the old form before your next renewal. There is no automatic importer, but our team will rebuild your existing forms for free when you upgrade to a paid plan - send us the public link and most are live within 24 hours.
