object0

A free and open-source desktop S3 bucket manager.

Manage objects across AWS S3, Cloudflare R2, DigitalOcean Spaces, MinIO, Backblaze B2, Google Cloud Storage, and any S3-compatible provider from a single, fast, cross-platform desktop app.

Built with Tauri · Rust · Bun · React · Tailwind CSS · daisyUI · Zustand
