colcon-notification
Extension for colcon to provide status notifications.
Decision gist · record as of 2026-08-14
Yes, if you use colcon and want build notifications. The low install friction, active maintenance, permissive license, and zero known vulnerabilities make it a safe addition. The Alpha status means notification behavior may change, but that's unlikely to break existing workflows. Install it if desktop notifications would improve your build workflow; skip it if you prefer terminal-only feedback.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires colcon-core to be installed and configured; notify2 on Linux/macOS and pywin32 on Windows must be available on your system.
- Low friction install with a pure Python wheel.
- Actively maintained with recent commits.

Verify before relying
pip install colcon-notification
Then run colcon as normal:
colcon build
Notifications will be sent automatically via your system notification daemon.- Whether notify2 and pywin32 are automatically installed on all platforms or require manual setup
- Specific notification behavior differences across Windows, macOS, and POSIX systems
- Whether the extension requires colcon-core to be already installed and configured
What it is and what it does
colcon-notification is a plugin for colcon-core that intercepts build events and sends them as desktop notifications to your system. It works across Windows, macOS, and Linux by delegating to platform-specific notification libraries (pywin32 on Windows, notify2 on POSIX systems). When you run a colcon build, instead of watching the terminal, you can receive system notifications about build progress and completion status.
The package is designed as a colcon-core extension, so it integrates directly into the colcon workflow without requiring changes to your build commands. It has been in active development since 2018 and is currently in Alpha status, meaning the notification behavior and API may still evolve. The low install friction and minimal dependencies make it a lightweight addition to an existing colcon setup.
Use it for
- Get desktop alerts when a long colcon build finishes, so you don't have to monitor the terminal
- Receive notifications on build failures or warnings without keeping the build window in focus
- Integrate colcon status into your system notification center on macOS or Windows
- Monitor multiple parallel builds via system notifications instead of terminal tabs
