Bring your own provider in five minutes
Marcus Lee1 min read
One of the things people love most about Space is that you don't have to store your files with us. If you already have storage you trust, Space can use it directly — we just handle the encryption, sync, and apps.
What you'll need
- An S3-compatible bucket (AWS S3, Backblaze B2, Cloudflare R2, MinIO, and more)
- Access credentials with read/write permissions
- The Space app on at least one device
Step by step
- Open Settings → Storage and choose Bring your own provider.
- Paste your bucket endpoint, region, and access keys.
- Space runs a quick connectivity check and creates an encrypted namespace.
- Pick which folders sync to the bucket.
- That's it — your files are now stored on infrastructure you own.
What Space does and doesn't see
Because everything is end-to-end encrypted before upload, your provider only ever stores opaque encrypted blobs. Even we can't read them. You pay your provider directly for the underlying storage, and there are no Space storage fees on top.
Prefer to keep it entirely local?
If you'd rather not use any cloud at all, install the companion app and keep everything on your own machine. No account, no bucket, no fees — just install it and you're done.
