forms.app vs Formstack

forms.app is an online form, survey and quiz builder launched in 2018 with a mobile-first focus. It reports 4M+ users in 170+ countries; its company, Forms App OÜ, is based in Tallinn, Estonia, and the product is made and hosted in the EU. The core job is to let anyone build good-looking forms quickly, collect responses and payments, and pass the data on to other tools.

Forms can be generated with AI or started from 5,000+ templates, using 30+ field types including signature and payment fields. Conditional logic shows or hides questions and routes people to different endings, and auto-scoring turns forms into quizzes and tests. Responses can be analysed with AI insights and sent to 500+ integrations such as Zapier, Google Drive, Slack, Notion and HubSpot. The free plan allows 5 forms with unlimited responses and team members; Basic raises this to 25 forms and removes branding, Pro unlocks unlimited forms, custom CSS and multilingual forms, and Premium adds 1 TB storage, custom domains and partial responses.

forms.app suits small businesses, educators and freelancers who want unlimited responses on a free or low-cost plan. Jotform has more enterprise features such as HIPAA and approvals, Typeform has stronger conversational design, and Tally offers a more generous free tier for simple forms.

Buying tip: from Turkey and the EU the pricing page shows euros, so US visitors may see different USD prices. Yearly plans are much cheaper than monthly, and paid plans carry a 90-day refund guarantee.

Formstack is a no-code forms and workflow platform founded in 2006 in Indianapolis by Ade Olonoh. Over the years it added Formstack Documents (from the WebMerge acquisition) and Formstack Sign, and bought Formsite. In 2025 the company renamed itself Intellistack and moved its headquarters to Denver, but Formstack products continue to be sold and supported under their own brand.

Formstack Forms covers drag-and-drop forms with conditional logic, payments, approval workflows, HIPAA-ready data handling, data encryption and offline collection through the Formstack Go mobile app. Documents turns submissions into filled PDFs or Word files, and Sign collects legally binding signatures, so a typical flow runs from intake form to generated contract to signature. Plans start with Forms for one builder user, Suite bundles all three products for three users, and Enterprise and Salesforce Solutions are quoted.

Formstack fits healthcare, education, government and financial teams that care about compliance and want forms, documents and signatures from one vendor. Jotform offers far more templates at lower prices, Typeform is better for conversational marketing forms, and Fillout gives modern forms with a generous free plan. Formstack has no free plan and per-form submission caps.

For Salesforce users, the native Salesforce forms product is the main reason to choose Formstack. Use the 14-day trial to confirm the submission limit per form fits your volume.
