# Kybl

> Kybl is a free, fast desktop app (macOS, Windows, Linux) for S3-compatible object storage. It lets you browse, upload, download, share and sync files on Amazon S3, Cloudflare R2, Hetzner Object Storage, Backblaze B2, Wasabi, DigitalOcean Spaces, MinIO, Ceph and any other S3 server. Built with Rust and Tauri.

Kybl (pronounced "kibble", from the Czech and Slovak word for bucket) is a native desktop client. You bring your own bucket; Kybl talks to your storage directly and stores secret keys in the operating system keychain, never in a file.
