A no-code workflow platform for mid-size and enterprise teams that bundles forms, document generation and e-signature, with a deep Salesforce integration. Here's how it stacks up against FormBuilder on pricing, features, and fit — so you can pick the right tool for the forms you actually build.
100 responses / month free · No credit card · Held responses never lost
The short answer
Choose Formstack when forms are one step in a larger process — generated documents, e-signatures, approvals, Salesforce records — and your organisation has the budget and compliance requirements to match. Choose FormBuilder when you need well-designed everyday forms fast, want a free plan or a $39 flat rate, and prefer an AI-assisted builder over an enterprise suite.
Overview
Formstack started as an online form builder in 2006 and has grown into a workflow suite: Formstack Forms (the builder), Formstack Documents (merge submissions into PDFs, Word files and contracts), and Formstack Sign (e-signature). The pitch is that one platform can take a request from intake form to generated document to signed agreement without code, which is why it sells mainly to operations, HR, healthcare and higher-ed teams.
The form builder itself is capable rather than flashy: drag-and-drop fields, conditional logic, multi-page forms, calculations, save-and-resume, payments (Stripe, PayPal, Authorize.net and others), workflows with approvals, and 300+ integrations. Its Salesforce apps are a genuine differentiator — forms that read and write Salesforce records natively and can live inside Experience Cloud — and it offers HIPAA compliance, PCI and SOC 2 for regulated buyers.
It is priced for organisations, not individuals. There is no free plan, only a 14-day trial. The entry Forms plan is $83 a month billed annually ($99 monthly) for a single builder seat and 25 forms, and the Suite that includes Documents and Sign is $250 a month billed annually. HIPAA is an add-on on those tiers and included on Salesforce and Enterprise plans, which are quoted.
FormBuilder is an AI-first form builder with a generous free plan, held (never lost) responses, and 6,000+ integrations. You describe the form you need, the AI generator drafts it, and you refine it in a drag-and-drop editor with conditional logic, multi-page layouts, file uploads, signatures and calculations. Every response can be routed to 6,000+ apps through Zapier or webhooks. The free plan includes 100 responses a month — and if a form gets busier than that, the extra responses are held safely rather than rejected, unlocking the moment you upgrade to Pro ($39 / month for 10,000 responses).

Honest assessment
A fair read of both sides. If the strengths column describes your work, Formstack may genuinely be the better fit.
A submission can trigger a merged PDF or contract and route it for signature and approval without leaving Formstack. For HR onboarding, admissions or contract intake this replaces two or three separate tools.
Formstack for Salesforce builds forms from Salesforce objects, prefills and writes back records, and runs inside Experience Cloud. Few form builders go this deep.
HIPAA compliance with a BAA, PCI, SOC 2 and field-level encryption are available, plus data residency options — the boxes procurement teams ask about.
Approvals, save-and-resume, partial submissions, workflow steps assigned to different people, and a long list of payment gateways reflect nearly two decades of enterprise use.
The cheapest plan is $83 a month billed annually for a single seat, and the trial lasts 14 days. For a small business or a one-off form the price is hard to justify.
The Forms plan includes one builder user; more collaborators, HIPAA, and Documents or Sign volume all cost extra, so the effective price is usually well above the headline number.
The editor is functional but the UI and default form styling look their age, and there is no prompt-to-form AI generator at the heart of the workflow.
Suite, workflows and Salesforce apps are powerful, but a team that just needs a contact or registration form ends up learning an enterprise product.
Switching
Most teams migrate a handful of forms in an afternoon. Here's the practical path.
In Formstack, open each form → Submissions → Export → CSV or Excel. Download any uploaded files you need to keep before your subscription ends.
Paste each Formstack field list into FormBuilder's AI generator; it drafts the fields, types and required flags. Rebuild conditional logic and page breaks in the editor.
Reconnect Salesforce, Google Sheets, Slack or your email tool through Zapier (6,000+ apps) or webhooks. For payment fields, connect your Stripe account in Settings → Payments.
Replace Formstack embed codes and shared links with your FormBuilder ones, and redirect any old URLs before you cancel.
Questions
For everyday forms — lead capture, registrations, applications, intake, surveys — yes. FormBuilder has a drag-and-drop and AI-assisted builder, conditional logic, multi-page forms, file uploads, Stripe payments, webhooks and Zapier, with a free plan and a $39 Pro plan. Formstack is still the better fit if you need document generation, e-signature workflows or native Salesforce forms.
Formstack Forms is $83 a month billed annually or $99 month-to-month for one builder user, 25 forms and 1,000 submissions per form. The Suite with Documents and Sign is $250 a month annually ($299 monthly). Salesforce and Enterprise plans are custom quoted. There is no free plan, only a 14-day trial.
No. Formstack offers a 14-day free trial of its Forms product with no credit card, after which you need a paid plan starting at $83 a month billed annually. FormBuilder's free plan includes 3 forms and 100 responses a month indefinitely.
Formstack is an enterprise workflow platform where forms feed document generation, e-signature and approvals, with deep Salesforce and HIPAA options and pricing from $83 a month. FormBuilder is a lighter, AI-first form builder for businesses that need good forms quickly, with a free tier and a flat $39 Pro plan for 100 forms and 10,000 responses.
Yes. Formstack offers HIPAA compliance with a BAA as a paid add-on on its Forms and Suite plans and includes it on Salesforce and Enterprise plans. FormBuilder's HIPAA plan with BAA support is $99 a month and is currently rolling out.
You can export submissions from each Formstack form as CSV or Excel. Form structures cannot be transferred directly, but you can paste the field list into FormBuilder's AI generator to recreate the form in seconds, then add logic and pages.
Yes. Formstack for Salesforce is a native app that builds forms from Salesforce objects and writes records back directly. FormBuilder connects to Salesforce through Zapier or webhooks, which is fine for creating leads and contacts but not for deep object-level workflows.
Formstack limits submissions per form (1,000 on the Forms plan) and expects you to upgrade for more volume. On FormBuilder, responses beyond your plan's monthly limit are held rather than dropped — the form keeps working and held responses unlock as soon as you upgrade.
