A focused file-upload SDK for full-stack TypeScript apps versus a general-purpose S3-compatible store bundled with the wider Supabase platform.
Pick UploadThing when uploads are the feature — you want a typed React SDK, presigned URLs, and a managed bucket that just works without writing your own upload pipeline. Pick Supabase Storage when you're already on Supabase, want storage in the same project as your auth and Postgres, and prefer a generic S3-compatible API you can swap out later.
