## What it is
Pingora is a Rust framework from Cloudflare for building fast, reliable, and programmable network services such as HTTP proxies and load balancers. It is battle-tested at Cloudflare, serving tens of millions of requests per second, with support for HTTP 1/2, gRPC, WebSocket proxying, TLS, and graceful reloads.

## Use cases
- build a custom reverse proxy in Rust
- build a programmable load balancer with failover
- replace nginx with a memory-safe proxy
- proxy gRPC and websocket traffic
- build a high-performance HTTP server at internet scale
- implement custom load balancing strategies

## When to choose
- you need a highly customizable, memory-safe alternative to C/C++ proxies like nginx
- performance and security are top priorities for your network service
- you need HTTP/1, HTTP/2, gRPC, or websocket proxying with graceful reloads

## When to avoid
- you need a turnkey proxy with config-file setup rather than writing Rust code
- your primary platform is Windows, which only has preliminary support
- you need stable caching APIs, which are still experimental and volatile

## Facets
- artifact type: framework
- maturity: stable
- function: http-server, proxy, load-testing, caching, websocket, middleware, routing
- domain: networking, backend, web-development, performance, developer-tools
- platform: rust, cross-platform
- tags: async-rust, reverse-proxy, load-balancer, tls, grpc-proxy, graceful-reload, cloudflare, linux, macos
