A tiny, fast WebSocket library for Go implementing RFC 6455 with a zero-copy, low-level API plus higher-level helpers in the wsutil package. It passes the Autobahn Test Suite and is designed for efficient buffer reuse across connections.

Use cases

• build a websocket server in go
• handle websocket connections with minimal allocations
• implement custom websocket frame handling
• upgrade http connections to websocket
• stream websocket messages with buffer reuse
• write a high-performance realtime backend in go

When to choose

• you need maximum performance and control over websocket I/O buffers
• you want a dependency-light RFC 6455 implementation in Go
• you need low-level frame access to build custom protocol logic

When to avoid

• you want a batteries-included websocket framework with rooms, pub/sub, or automatic reconnection
• you prefer a simpler high-level API like gorilla/websocket or nhooyr/websocket
