Deploy and Host Public Bucket URLs on Railway

Serve files from Railway Buckets using public, static URLs without a proxy. The service redirects to a presigned bucket URL, which then delivers the file to the user. This avoids paying for public egress when serving the file.

Demo

https://bucket-public-presigner-demo.up.railway.app/duck.png

Open the link to view the file. Your browser will redirect to another URL: a presigned URL that grants temporary access to the object in your bucket. While this temporary URL will expire (by default after 1 hour), the original public URL will never expire.

About Hosting Public Bucket URLs

Presigned URLs are temporary, signed URLs that grant time-limited access to specific objects in your bucket. This template generates them automatically and redirects requests to them. Users typically don't notice that the URL changed.

With S3-style storage, it’s common to use static URLs that perform an authorization check before redirecting to a presigned URL. This template skips the authentication and redirects to the file immediately.

Caution: Only use this template if every file in your bucket should be publicly accessible. If you need private files, use separate buckets or implement your own authenticated redirects. For an example implementation, check out the source code of this template: https://github.com/timomeh/s3-public-presigner

Common Use Cases

Dependencies for Public Bucket URLs Hosting
