Deploy and Host S3 Proxy on Railway

A high-performance S3 proxy with intelligent caching that transforms any S3 bucket into a blazing-fast CDN. Features smart HTTP caching, stale-while-revalidate strategy, and comprehensive monitoring for serving static assets at scale.

About Hosting S3 Proxy

S3 Proxy is a lightweight Go application that sits between your users and S3 bucket, providing CDN-like performance through intelligent caching. It implements proper HTTP caching semantics with ETags, conditional requests, and background revalidation. The proxy significantly reduces S3 costs and latency by serving cached content from memory while ensuring freshness through smart cache invalidation. Railway's auto-scaling perfectly complements the proxy's stateless architecture, automatically handling traffic spikes while maintaining sub-millisecond cache hit response times.

Common Use Cases

Static Asset CDN: Serve images, CSS, JS, and other static files with CDN performance
Media Streaming: High-performance delivery of videos, audio, and large media files
File Downloads: Accelerate software downloads, documents, and user-generated content
Image Optimization: Serve optimized images with proper caching headers
Cost Reduction: Dramatically reduce S3 bandwidth costs through intelligent caching
