Supabase Storage

Judgement

What it is

Building block

What it does

The S3-compatible storage service used by Supabase, which keeps object metadata and access policies in Postgres and supports resumable uploads and image transformations.

Adopt it when

You self-host Supabase or want file storage whose permissions are enforced with Postgres row-level security.

Watch out

It is built for the Supabase stack, so running it on its own means wiring up its Postgres and auth expectations yourself.

Ready for

Production-ready

Runs as

Self-hosted server and cloud service

Built with

TypeScript, Fastify and PostgreSQL

How established

Established: started 5 years ago, latest release v1.89.13.
