Bitbucket Image Diff Heatmap

About

Enhance your Bitbucket pull request reviews with visual image diff tools.

When reviewing PRs that contain image changes, this extension adds a toolbar with four viewing modes:

• Normal - The default Bitbucket side-by-side view
• Heatmap - Color-coded overlay highlighting exactly where pixels changed, from blue (minor) to red (major). Adjustable opacity slider included.
• Diff Only - Isolates only the changed pixels on a dark background, making subtle differences easy to spot
• Slider - Before/after comparison with a draggable slider to scrub between versions

Also shows pixel-level change statistics: how many pixels changed and the percentage of the image affected.

Perfect for designers, frontend developers, and anyone reviewing visual changes in Bitbucket pull requests.

Works automatically on any Bitbucket pull request that contains image file changes. No configuration needed — just install and go.
