One viewer.
Every S3 workflow.
S3 Viewer is a developer-first dashboard for AWS S3, Cloudflare R2, MinIO, Backblaze B2, and Wasabi — built to replace the AWS console for the things you do every day. Pick the workflow that matches yours.
Multi-cloud
AWS S3, Cloudflare R2, MinIO, B2, and Wasabi — same sidebar, same file browser, one server at a time.
Sharing without AWS
Email-invite clients and execs to a clean browser view of one bucket — revocable in one click, no IAM.
Team workspaces
Per-bucket roles, no per-person IAM, and one-click off-boarding without rotating any keys.
Better S3 browser
Browse and preview across providers, with guarded rename and multi-select deletion on AWS S3.
Cloudflare R2
Browse, preview, download, upload, and share Cloudflare R2 files with your team.
Security
Credentials encrypted in your browser, zero object retention, MIT open source, fully self-hostable.
