Colab Notifier

Get real-time notifications on your phone when a Google Colab notebook fails or disconnects from the runtime.

Colab Notifier helps you monitor long-running Google Colab notebooks without constantly checking your browser. The extension watches your active Colab notebook and sends instant Telegram notifications to your phone when a cell execution fails or when the runtime disconnects. This is especially useful for long training jobs, experiments running unattended, and overnight or background executions. How it works: The extension runs only on Google Colab notebooks. It detects failures and disconnects in real time and sends alerts securely using your own Telegram bot. Privacy and security: Colab Notifier does not track users, does not collect analytics, and does not show ads. No data is sold or shared. Telegram credentials are stored locally using Chrome storage and are used only to send notifications.
