Simple S3 Browser

Simple S3 Browser lets you connect to any S3‑compatible object storage (AWS S3, MinIO, Cloudflare R2, Wasabi, DigitalOcean Spaces, OVH, Vultr Objects, Storj, Filebase, and more) to browse, preview, upload, download, share, and search your files—all from your phone.

Highlights

- Connect multiple endpoints and buckets; switch instantly between profiles

- Optional biometric lock per bucket to keep your data private

- Fast browsing with folder navigation, pagination, multi‑select, copy/move, create folders

- Upload files and folders; download and share files with other apps

- Built‑in viewers/players: images (gallery), audio (playlist), video (subtitles on Android), PDF, Markdown, TTS read‑aloud for text/markdown, EPUB, common office/open‑document types, and popular archives

- Transfers tab to monitor and manage uploads/downloads

- Powerful global search across all folders using an on‑device index:

- Handles very large buckets (1,000,000+ objects)

- Pause/Resume with throughput and ETA

- Resumes after app restarts; progress is persisted on device

- Works with any S3‑compatible provider

Privacy & Security

- The app connects directly to your configured S3 endpoints

- Credentials stay on your device; nothing is sent to our servers

- You control which endpoints and buckets you add

Notes

- Initial global indexing depends on your network speed and bucket size; once built, searches are instant

- Some embedded viewers may vary by platform capabilities
