Airtable vs Supabase: Backend Comparison for 2025

When building modern apps or internal tools, one of the first decisions you’ll face is choosing the right backend or database-as-a-service platform.

Two popular options are Airtable and Supabase. While both offer a fast start and developer-friendly experiences, they serve very different use cases. Let’s compare their features, strengths, limitations, and ideal use cases, so you can confidently choose the right tool for your project.

• Authentication (OAuth, magic links, etc.)
• Row-level security with SQL policies
• Realtime via websockets
• Edge functions (Deno/JavaScript)
• File storage + CDN

Strengths:
