The bottom line

Pricing: Airtable is completely free (Free for 1000 records), which makes it the obvious pick if budget is the top concern. Supabase starts at $25/mo, but Free for 2 projects, pauses after inactivity. That cost buys you a more polished or feature-rich experience, so it comes down to whether the extras justify the spend.

Feature gaps: Supabase offers Auth, Edge Functions and Postgres that Airtable lacks. Airtable brings Automations, Extensions and Interfaces that Supabase does not have.

Team fit: Both tools target any size teams, so the decision hinges on features and workflow fit rather than scale.

Open source: Supabase is open source, meaning you can self-host, audit the code, and avoid vendor lock-in. Airtable is proprietary — you are trusting the vendor with your data and uptime.

Where each tool shines: Supabase's biggest strengths are: full postgres database with sql access and extensions. open source with self-hosting option for full control. Airtable's biggest strengths are: includes views as a core feature, purpose-built for database workflows. built-in automations handle repetitive tasks like status changes and assignments.

Watch out for: With Supabase, users commonly note that free tier pauses inactive projects after one week. With Airtable, the main complaint is that free plan exists but key features are locked behind the paid upgrade.
