About Colab Rewind
Colab Rewind: The Undo Button for Google Colab
Accidentally deleted a perfect block of code? Ran a cell that ruined your model and forgot your hyperparameter tweaks? Colab Rewind is an invisible safety net that automatically saves your execution history as you work.
Features:
Automatic Checkpoints: Every time you execute a cell, the code is saved locally in the background.
Time Travel: Click the new ↺ Rewind button injected into any Colab cell to view a dropdown of your past runs.
Pin Important Code: Manually pin major milestones so they are never overwritten.
Instant Restore: Click "Restore" to instantly inject old code back into your active cell.
Dark Mode Native: Beautifully adapts to Colab's light and dark themes.
Privacy First (No Cloud Needed):
Your code is your business. Colab Rewind uses your browser's native IndexedDB to store your history entirely locally on your hard drive. Zero data is sent to external servers, and no cloud account is required.
