PyChromecast
Python module to talk to Google Chromecast.
Decision gist · record as of 2026-08-14
Yes. Active maintenance, low install friction, permissive license, and no known vulnerabilities make this a solid choice for Chromecast integration. Requires Python 3.11+ and network multicast support; verify those constraints match your environment before installing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11+.
- Multicast UDP on port 5353 must be available on the network for device discovery to work.
- Low friction install with three straightforward runtime dependencies (protobuf, zeroconf, casttube).

What it is and what it does
PyChromecast is a Python library for communicating with Google Chromecast and Cast-enabled devices on a local network. It handles device discovery via mDNS, connection management, and playback control through the Chromecast API v2. The library abstracts the protocol details so you can discover devices by name, start media playback, pause or resume, and extend functionality by registering custom controllers for app-specific namespaces.
The package is built on protobuf for message serialization, zeroconf for mDNS discovery, and casttube for additional protocol support. It's designed for Python 3.11+ and requires network multicast capability. Common use cases include automation frameworks (notably Home Assistant), media center integrations, and multi-room audio control.
Use it for
- Discover and list all Chromecast devices on a network, then connect to specific ones by friendly name.
- Play online media files on a Chromecast and control playback (play, pause, seek) programmatically.
- Build automation routines that cast media to different rooms based on time or events.
- Extend support for custom Chromecast apps by implementing controllers for unsupported namespaces.
- Monitor and control multi-room audio setups with multiple Cast Audio devices.
