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
Fillout is a newer form builder built around one idea: your form should live on top of the database you already use. Connect an Airtable base, Notion database, HubSpot object, Salesforce record or Google Sheet, and Fillout maps fields both ways — it can prefill from existing records, create new ones, and update them on submit. For teams running operations out of Airtable or Notion it is often the missing "front door" for their data.
The builder itself is polished and quick, with a large field catalogue (50+ types including payments, scheduling, signatures and PDF generation), conditional logic, calculations, multi-page flows, quizzes and a growing set of AI features for drafting forms. It also supports login-gated forms, partial-submission capture and PDF output, which pushes it toward internal tools and client portals as much as public forms.
MightyForms is a drag-and-drop online form builder aimed at small businesses that needed lead-capture, intake, order and registration forms without writing code. Its signature idea was that a form should never lose a lead: every keystroke was saved as a partial submission, abandoned forms could be recovered with automated follow-up emails, and respondents could resume where they left off. Stripe and PayPal payments, autoresponders, email/SMS notifications, PDF export and Zapier connectivity rounded out the product.
In May 2026 FormBuilder acquired MightyForms. The MightyForms app remains available at its existing login for current customers, and nothing about existing accounts, forms, submissions or billing has been moved automatically. FormBuilder.com is now the home for the MightyForms public templates and educational resources, and it is where we recommend building new forms.

Fillout is a fast, modern form builder whose signature trick is writing responses straight into Airtable, Notion, HubSpot, Salesforce and Google Sheets — with a very generous free plan. MightyForms is the drag-and-drop form builder known for abandoned-form recovery and partial submissions — now part of FormBuilder. Fillout is best for teams that run on Airtable, Notion, HubSpot or Salesforce and want forms that write directly to those records; MightyForms is best for existing MightyForms customers who want to keep using the app they know.
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.
