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

S3 Bucket Viewer (Secure) is a lightweight web UI for browsing an S3-compatible bucket on Railway. It deploys s3manager as the file explorer and places caddy-zero-trust in front as an authentication gateway, so the viewer can be exposed safely while the S3 browser stays on Railway’s private network.

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.
