CppNet is a cross-platform, multithreaded C++11 network library implementing the proactor pattern for asynchronous TCP I/O. It uses epoll, wepoll (IOCP), and kqueue under the hood and exposes a small socket-like callback API supporting IPv4 and IPv6.

Use cases

• build a high-performance TCP server in C++
• write asynchronous network clients and servers with callbacks
• implement a simple HTTP server on Linux, Windows, and macOS
• handle thousands of concurrent socket connections efficiently
• build an RPC or file-transfer service over TCP
• replace raw epoll/kqueue/IOCP code with a portable abstraction

When to choose

• you need a lightweight, portable async TCP library in modern C++ with minimal dependencies
• you want proactor-style asynchronous callbacks similar to system socket APIs
• you need cross-platform support for epoll, kqueue, and IOCP/wepoll from one codebase
• you want per-socket memory pooling and time-wheel timers built in

When to avoid

• you need full-featured application protocols like HTTP/2, TLS, or WebSockets out of the box
• you prefer a large, widely-adopted ecosystem like Boost.Asio with extensive documentation
• your project requires UDP, QUIC, or other non-TCP transports
• you need commercial-grade support or a very large contributor community
