Souin is an HTTP cache system for reverse proxies and web services.
Written in Go, it is designed to cache HTTP responses in front of upstream applications and can be deployed in different ways depending on your stack. The project’s documentation covers use as a reverse-proxy cache along with integrations for a range of servers, gateways, and Go web frameworks.
This is free and open source software.
Key Features
- Can be deployed as a standalone reverse-proxy cache or integrated as a plugin or middleware.
- Implements standards-aware HTTP caching features including Vary handling, request coalescing, stale cache-control support, and Cache-Status headers.
- Provides cache management and invalidation through its Souin API, including surrogate-key based invalidation.
- Exposes Prometheus metrics for monitoring cache behaviour and performance.
- Supports ESI tags and uses a dedicated YAML configuration file for setup.
- Cross-platform support – runs on Linux, macOS, and Windows.
