Brows3 is a high-performance desktop client for Amazon S3 and S3-compatible object storage. It uses a Rust core and Tauri-based interface, with prefix-aware navigation, caching and a virtualized object table intended to keep large buckets responsive.
Besides Amazon S3, Brows3 supports S3-compatible services including MinIO, Cloudflare R2, Wasabi, STACKIT Object Storage and DigitalOcean Spaces. It also provides built-in file editing, previews, bulk operations and deep search.
This is free and open source software.
