A minimal and idiomatic WebSocket library for Go, originally by nhooyr and now maintained by Coder. It offers zero-dependency, context-first WebSocket client and server implementations with JSON helpers, compression, and Wasm support.

Use cases

• add websocket support to a go http server
• build a real-time chat backend in go
• stream json messages over websockets in go
• compile a websocket client to wasm
• implement ping/pong keepalive for websocket connections
• replace gorilla/websocket with a maintained minimal library

When to choose

• you want a zero-dependency, idiomatic Go WebSocket library with first-class context.Context support
• you need RFC 7692 permessage-deflate compression or JSON message helpers
• you target Wasm or want zero-alloc reads and writes

When to avoid

• you need HTTP/2 WebSocket support, which is still on the roadmap
• you require graceful shutdown or heartbeat helpers that are not yet implemented
• you need a batteries-included WebSocket framework rather than a minimal library
