## What it is
Nuster is a high-performance HTTP proxy cache server and RESTful NoSQL key-value cache server built on top of HAProxy, written in C. It is 100% HAProxy-compatible and uses HAProxy ACLs to define fine-grained caching policies based on request, response, or server state.

## Use cases
- cache dynamic and static HTTP responses like varnish or nginx fastcgi cache
- speed up my api by caching responses at a reverse proxy
- use a fast key-value cache over HTTP instead of memcached or redis
- load balance backend servers with built-in caching
- purge or invalidate cached HTTP responses via a management API
- store per-user data in a RESTful cache using cookies or headers

## When to choose
- you want HAProxy compatibility plus caching in a single high-performance proxy
- you need fine-grained cache rules based on headers, cookies, URI, or server state
- you want a RESTful HTTP key-value cache usable from any language
- benchmarks matter and you need faster caching than nginx or varnish

## When to avoid
- you need a actively developed project with recent releases and ongoing maintenance
- you need TLS termination features beyond what HAProxy provides
- you prefer a cache with a large ecosystem of plugins and community modules
- you need a managed or cloud-native cache service
