Hey Product Hunt,
I built LocalDiff Desk because I kept needing a quick way to compare screenshots, design revisions, and product images without sending files to another server.
The tool runs locally in your browser. You can drop in two images, switch between side-by-side, overlay, difference, blink, and swipe views, tune the sensitivity, and export the result.
The main promise is simple: no account, no upload, no stored files.
I’d love feedback from designers, QA folks, frontend developers, and anyone who reviews before/after images often. What comparison mode or workflow would make this more useful for you?
