## What it is
OpenNJet is a high-performance, lightweight web application and proxy engine written in C, designed as a cloud-native service mesh data plane. It offers dynamic configuration loading, active health checks, cluster high availability, declarative APIs, HTTP3, WAF integration, and a CoPilot framework for extensible control/data plane separation.

## Use cases
- replace nginx with a cloud-native proxy engine
- run a service mesh data plane with high performance
- set up an api gateway with dynamic config reload
- load balance http traffic with active health checks
- add a web application firewall to my reverse proxy
- support http3 and chinese national crypto (SM) algorithms
- build a highly available multi-master proxy cluster

## When to choose
- you need an nginx-like proxy with dynamic configuration and declarative APIs
- you want a service mesh data plane faster than Envoy
- you need built-in WAF, HTTP3, or Chinese national cryptography support
- you want Lua/Python programmability and a plugin framework

## When to avoid
- you need a mature ecosystem with extensive third-party modules like nginx
- your stack is Windows-only
- you prefer Envoy/Istio's standard xDS ecosystem tooling

## Facets
- artifact type: application
- maturity: active
- function: http-server, proxy, api-gateway, service-discovery, middleware, security, monitoring, plugin-system
- domain: web-development, backend, microservices, cloud-computing, networking, security, self-hosted
