AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

simple-websocket provides a straightforward WebSocket server and client implementation for Python, enabling bidirectional communication over WebSocket connections with minimal setup.

Installation is low-friction with a single runtime dependency (wsproto) and an active maintenance status. The package was last updated 2024-10-10 with recent repository activity (last commit 2026-05-14), indicating ongoing support.

The package carries a permissive MIT license classification, meaning you can use, modify, and distribute it with minimal legal restrictions—typical for open-source libraries.

Usage

pip install simple-websocket

from simple_websocket import Server

ws = Server(environ)
data = ws.receive()
ws.send(data)

Requires Python 3.6 or later; WebSocket connections must be initiated within a valid WSGI or similar web environment context.

Verdict: simple-websocket is a well-maintained, permissively licensed WebSocket library with low installation friction and no known vulnerabilities. Its active status, top-1000 popularity tier, and straightforward dependency chain make it a reliable choice for adding WebSocket support to Python applications.

Needs verification
