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.
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.

Questions
Fillout's entry paid plan (Starter at $15 / month (annual)) is cheaper than FormGrid's (Plus at $29 / month (per directories)). Both offer a free plan (1,000 responses / mo · unlimited forms & seats · 20 MB uploads · Fillout branding) and a free plan (Unlimited forms & responses · AI drafting · custom themes · logic · 10 MB uploads · unlimited team members · FormGrid badge) respectively. Note the plans differ in limits — see the tables above. FormBuilder Pro, for reference, is $39 / month for 10,000 responses.
Fillout offers a free plan (1,000 responses / mo · unlimited forms & seats · 20 MB uploads · Fillout branding). Prices shown are per month on annual billing (about 20% less than monthly). All plans include unlimited forms and unlimited seats; the meaningful limits are monthly responses and features.
FormGrid offers a free plan (Unlimited forms & responses · AI drafting · custom themes · logic · 10 MB uploads · unlimited team members · FormGrid badge). The vendor pricing page shows plan contents but the dollar amounts we could confirm come from third-party listings (Plus $29, Business $79 per month); annual billing is advertised as saving up to 34%. Check vendor pricing before deciding.
Fillout payments: Yes (Stripe; free plan). FormGrid payments: No (Not an advertised feature). FormBuilder collects Stripe payments to your own account with no platform fee on every plan, including free.
Fillout HIPAA / BAA: Yes (Enterprise only). FormGrid HIPAA / BAA: No (No BAA offered). FormBuilder's HIPAA plan with BAA ($99 / month) is currently rolling out.
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. 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. Fillout is best for teams that run on Airtable, Notion, HubSpot or Salesforce and want forms that write directly to those records; 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.
