# Every bucket, one window

Amazon S3, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, Google Cloud Storage, MinIO or any other S3-compatible store by its endpoint. Browse a bucket like a folder and copy with F5.

[Open the full demo](https://anybucket.app/try?mode=s3)

- **A tile per provider:** Pick Amazon S3, Cloudflare R2, Backblaze B2, Wasabi, DigitalOcean Spaces, Google Cloud Storage or S3-compatible. Each gets its own badge.
- **Any endpoint:** Set an endpoint URL for MinIO and other stores, with **path-style** or virtual-hosted addressing.
- **Big files, multipart:** Large uploads go up in parts, and copies on the same server run server-side with **CopyObject**.
- **Secrets in your keychain:** The secret access key is stored in your login keychain, one item per bookmark.

## Questions, answered

### Does it work with Cloudflare R2?

Yes. Pick the Cloudflare R2 tile, enter your account ID and an R2 API token's access key, and AnyBucket builds the endpoint. See [Cloudflare R2 on a Mac](https://anybucket.app/guides/cloudflare-r2-mac).

### Does it work with Backblaze B2?

Yes, through B2's S3-compatible API. See [Backblaze B2 on a Mac](https://anybucket.app/guides/backblaze-b2-mac).

### My MinIO server lists nothing

Set the endpoint URL in the bookmark and turn on path-style addressing, which MinIO and most self-hosted stores expect.

### Can I copy from S3 to another provider?

Yes. Open one bucket in each pane and press F5: files stream between the two through a small spool on your Mac.
