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 search, cross-cloud copy when you need it.
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
One-click rename, Tab-autocomplete bucket-wide search, and Cmd-K — focused on the daily browsing layer.
Cloudflare R2
Rename, search, multipart upload, and team sharing on top of Cloudflare R2's S3-compatible API.
Security
RSA-4096 encrypted credentials, zero object retention, MIT open source, fully self-hostable.
