Your files. Your bucket. Your rules.
A file workspace that keeps every byte in storage you own. byos3 runs the sync, sharing and API; you keep the bucket and pay for the service, never per-gigabyte rent.

Bring your own bucket
Mount an S3, R2, B2, Wasabi, or MinIO bucket you already own. We store only the encrypted credentials, never your files.
Direct, fast transfers
Files move straight between your device and your bucket over short-lived presigned URLs. No middle hop, no per-gigabyte rent.
Live sync and sharing
A single-writer journal keeps every window and device in step in real time. Share a volume with a teammate by email.
Open, versioned API
Anything the app can do, an API key can do. Content-addressed blocks, cursor sync, and a documented HTTP surface.
