Drop-in replacement for Requests. Automatic HTTP/1.1, HTTP/2, and HTTP/3. WebSocket, and SSE included.

std_net.h` is a zero-dependency, header-only C/C++ networking library for TCP sockets. It abstracts cross-platform complexities (Windows/Linux/macOS/Android/FreeBSD) into a unified API for building clients/servers. Features include IPv4/IPv6 support (Happy Eyeballs), blocking/non-blocking I/O, timeouts, and RAII wrappers. MIT licensed.

Python implementation of the Happy Eyeballs Algorithm described in RFC 6555

AIR Native Extension (ANE) that supports HTTP/2, TLS 1.3, and the Happy Eyeballs algorithm (RFC 8305) for optimized connection performance. It allows custom HTTP methods and headers with progress callbacks across Windows, Android, macOS, and iOS.

Claude Code freezing, hanging, or stuck on 'thinking'? On some networks it's a degraded IPv6 path. Diagnose in 30s and fix by forcing IPv4 — one static Go binary, macOS/Linux/Windows.
