µWebSockets is a C/C++ web server library providing highly optimized HTTP and WebSocket handling with a built-in URL router and pub/sub features. It includes a seamless Node.js integration (uWebSockets.js) and is designed for demanding, high-throughput real-time applications.

Use cases

• build a high-performance websocket server
• serve http and websockets from one fast server
• real-time messaging for trading or chat apps
• pub/sub messaging over websockets
• embed a fast web server in a C++ application
• use websockets from Node.js with native performance

When to choose

• you need maximum throughput and low memory footprint for websocket or HTTP workloads
• you want a battle-tested, standards-compliant server with TLS 1.3 support
• you need built-in routing and pub/sub for real-time apps
• you want native-speed websockets in Node.js

When to avoid

• you want a batteries-included full web framework with ORM, templating, and ecosystem middleware
• your team cannot work with C/C++ APIs and Node.js bindings are insufficient
• you need extensive third-party middleware and plugin support
• you prefer a pure-JavaScript or pure-Python stack
