Modern form builder with Notion, Airtable, and database integrations
Fillout is a modern form builder focused on deep database integrations — connecting forms directly to Notion, Airtable, Supabase, and Google Sheets so that responses write to structured data sources rather than a proprietary form inbox. Its clean editor, no-code conditional logic, and direct database write capabilities make it the preferred form tool for teams building data-driven workflows with Notion and Airtable as their operational backbone.
Fillout is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Fillout's differentiator is database integration depth: where most form tools write responses to their own inbox and offer Zapier for further routing, Fillout writes directly to Notion databases, Airtable bases, Supabase tables, and Google Sheets — preserving field types, relationships, and data structure in the target system.
Fillout's Notion connection maps form fields to Notion database properties with type awareness — text fields map to title/text properties, select fields map to Notion select/multi-select, date fields map to Notion date properties, and file uploads attach to Notion file properties. Form responses appear as full Notion database pages with all properties populated — not just a text dump.
Fillout maps to Airtable fields with the same type awareness: linked record fields create relationships, select fields respect Airtable's option lists, and formula fields receive computed input. For teams using Airtable as their operational database, Fillout is a more direct data entry path than Airtable's own native forms, with better conditional logic and visual customisation.
Fillout's Supabase integration writes form data to Postgres tables directly via Supabase's API — useful for developer teams who have already chosen Supabase for their backend and want a polished form UI without building a custom form component. The integration respects Postgres data types and constraints.
Score: 7.7/10 — Best form builder for Notion and Airtable database integration; value proposition most compelling for teams using these specific platforms.
