Supabase
Open-source Firebase alternative built on PostgreSQL with realtime and auth
Overview
Supabase is an open-source backend platform providing a hosted PostgreSQL database, auto-generated REST and GraphQL APIs, realtime subscriptions, row-level security, authentication, storage, and edge functions. The entire stack can be self-hosted using Docker Compose with a single configuration file. It targets the same audience as Firebase but uses standard SQL.
Where it falls short of Airtable
- Self-hosted Docker Compose stack is complex: 8+ services including Kong, GoTrue, PostgREST, Realtime
- Studio table editor is less polished than Airtable UX for non-technical users
- Edge Functions are limited to Deno; no Node.js runtime in the self-hosted edition
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
