## Description

# Trio WebSocket

This library implements both server and client aspects of the [the WebSocket
protocol](https://tools.ietf.org/html/rfc6455), striving for safety,
correctness, and ergonomics. It is based on the [wsproto
project](https://wsproto.readthedocs.io/en/latest/), which is a
[Sans-IO](https://sans-io.readthedocs.io/) state machine that implements the
majority of the WebSocket protocol, including framing, codecs, and events. This
library handles I/O using [the Trio
framework](https://trio.readthedocs.io/en/latest/). This library passes the
[Autobahn Test Suite](https://github.com/crossbario/autobahn-testsuite).

This README contains a brief introduction to the project. Full documentation [is
available here](https://trio-websocket.readthedocs.io).

## AI interpretation — verify before relying

Implements WebSocket client and server using the Trio async framework, built on wsproto for protocol handling and passing the Autobahn Test Suite.

Verdict: A solid, well-tested WebSocket implementation for Trio with no known vulnerabilities and permissive licensing. The aging maintenance status and 534-day gap since last release warrant caution for new projects; consider it stable for existing deployments but evaluate alternatives like quart-trio if you need active development support.
