Deploy and Host S3 Bucket Viewer (Secure) - s3manager - S3 Browser on Railway

For browsing an existing S3-compatible bucket through a protected web interface on Railway, use S3 Bucket Viewer. It pairs s3manager with a Caddy Basic Auth gateway, keeping the file browser private behind authenticated HTTPS access. Supply your bucket endpoint, region and access credentials as documented below. This is a storage browser, not a replacement object-storage service or a source of free storage.

About Hosting S3 Bucket Viewer (Secure) - s3manager - S3 Browser

This template deploys two services: s3manager (the S3 web UI) and caddy-zero-trust (a Basic Auth reverse proxy). Configure your Railway Bucket credentials (ENDPOINT, REGION, ACCESS_KEY_ID, SECRET_ACCESS_KEY) and s3manager will connect to your S3-compatible storage. Then caddy-zero-trust publishes a single public URL and forwards authenticated traffic to s3manager over Railway Private Networking. Keep s3manager private (no public domain) so only the proxy is reachable from the internet.

Common Use Cases

Inspect and manage objects in a Railway Bucket (upload, download, delete).
Quickly validate that your app is writing files to S3-compatible storage.
Provide temporary, password-protected access for admins/support.
