Supabase is the open-source Firebase alternative, providing a full backend stack built on PostgreSQL. The platform offers a managed Postgres database with real-time subscriptions, authentication, instant APIs (REST and GraphQL), edge functions, file storage, and vector embeddings. Supabase has grown rapidly to power over 1 million databases, attracting developers who want the convenience of Firebase with the power and flexibility of PostgreSQL and open-source tooling.
Supabase outages typically involve database connection pooling issues (PgBouncer), authentication service disruptions, or edge function deployment failures. Because each project gets its own dedicated PostgreSQL instance, outages can be project-specific rather than platform-wide. Supabase Studio dashboard issues are usually separate from database availability. Real-time subscription failures often stem from WebSocket connection handling at the Realtime server level.
When Supabase is down, applications lose access to their PostgreSQL database, authentication system, and real-time subscriptions. REST API calls to the database return errors, user login flows break, and real-time features stop receiving updates. File storage uploads and downloads fail. Edge functions that handle server-side logic become unreachable. Applications built fully on Supabase experience complete backend failure.
Use this page to check Supabase platform availability. Since each Supabase project runs on a dedicated PostgreSQL instance, outages can be project-specific. Check status.supabase.com for platform-wide incidents and the Supabase dashboard for your project's specific health metrics.
Connection failures can result from platform outages, exhausted connection pool limits (each project has a PgBouncer connection pool), network issues, or paused projects on the free tier. Free-tier projects are paused after 7 days of inactivity. Check your project's connection pooler status in the Supabase dashboard.
Supabase uses dedicated PostgreSQL instances per project, so one project's issues rarely affect others. Firebase shares infrastructure across projects. Supabase's open-source nature means you can self-host during outages. However, Supabase doesn't yet offer the same level of offline SDK persistence that Firebase provides.
Your data remains safe in the PostgreSQL database — Supabase outages typically affect access, not data integrity. Database backups run independently. Once service resumes, all data will be exactly as it was. For critical applications, consider setting up read replicas or point-in-time recovery for additional safety.
