Two popular form builders compared on the same 25-row feature matrix and pricing, with FormBuilder shown as a third column so you can see another option to consider.
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.
FormGrid is an independent form and survey builder whose pitch is looks and logic for free. The free plan includes unlimited forms and unlimited responses, an AI assistant that drafts a form (questions, logic and design) from a text description, custom themes, a flexible grid layout system, and a fairly deep logic set — conditional questions, repeatable sections, answer piping, calculations, hidden fields and page navigation. Responses land in a built-in analytics dashboard with CSV / XLSX export.
The paid tiers are about working with other people and looking like yourself. Plus ($29 / month as listed by third-party directories; annual billing saves up to 34%) adds team collaboration, custom emails, a custom domain, hiding the FormGrid badge, 30-day version history and 100 MB uploads. Business ($79 / month) adds workspaces, roles and permissions, 90-day history and 1 GB uploads. Integrations cover Zapier, Make, Airtable, Notion, Google Sheets and webhooks. Data is hosted in Europe and the product is GDPR-oriented.

Formstack is a no-code workflow platform for mid-size and enterprise teams that bundles forms, document generation and e-signature, with a deep Salesforce integration. FormGrid is a small, design-led form builder that gives away unlimited forms and responses with AI drafting, and charges only for team features, custom domains and badge removal. Formstack is best for operations, HR and admissions teams that need forms to feed documents, approvals and e-signatures; FormGrid is best for designers, makers and small teams who want unusually pretty forms for free.
FormBuilder is worth a look if you want an AI generator that drafts forms from a sentence, 100 free responses a month with overflow held rather than lost, Stripe payments with no platform fee, and a flat $39 / month Pro plan for 10,000 responses.
