storage

This is Supabase's file storage service built on top of S3. Picture a managed file system with built-in auth rules, image transformations, and resumable uploads. You set policies in SQL (same as your database RLS), and files respect the same auth you already configured.

Apache 2.0. The storage API supports presigned URLs, on-the-fly image resizing, and resumable uploads for large files using the TUS protocol.

Supabase's free tier gives you 1GB of storage and 2GB bandwidth. Pro at $25/mo bumps that to 100GB storage and 250GB bandwidth, with overage at $0.021/GB stored and $0.09/GB transferred. Image transformations cost extra at $5 per 100 origin images. Self-hosting is possible. The storage server is open source and runs against any S3-compatible backend (MinIO, R2, actual AWS S3). Self-hosted means unlimited storage, no bandwidth fees, but you manage the infra.

The catch: this is tightly coupled to the Supabase ecosystem. If you're not already on Supabase, there's no reason to use this over direct S3, Cloudflare R2, or similar. And the 1GB free tier is small; one app with user-uploaded images blows through that fast.
