Sairo

Sairo is a self-hosted, open-source web browser for S3-compatible object storage. It runs as a single Docker container with zero external dependencies — no databases, no microservices, no message queues.

It indexes your entire bucket into SQLite FTS5 and delivers full-text search in ~2ms across hundreds of thousands of objects. On a bucket with 134,000 objects and 38 TB of data, median search latency is 2.4ms — compared to ~14 seconds in the AWS S3 console.

Key features:

• Instant search across all objects with SQLite FTS5 indexing (1,300 objects/sec)
• File preview for 45+ formats including Parquet schemas, CSV tables, PDFs, images, and syntax-highlighted code — no download needed
• Password-protected share links with configurable expiration
• Version management — browse, restore, and purge object versions and delete markers
• Storage analytics dashboard with per-folder growth trend charts
• Multi-endpoint support — connect AWS S3, MinIO, Cloudflare R2, Wasabi, Backblaze B2, Ceph, and more from one dashboard
• Role-based access control with per-bucket permissions
• Two-factor authentication (TOTP), OAuth (Google, GitHub), and LDAP
• Full audit log with 37 tracked actions
• CLI tool with 24 commands and OS keyring credential storage
• Dark mode with system preference detection
• 30+ keyboard shortcuts

Sairo works with any S3-compatible endpoint including AWS S3, MinIO, Cloudflare R2, Wasabi, Backblaze B2, Ceph, and Leaseweb. It deploys via Docker, Docker Compose, or Helm on Kubernetes.
