Go beyond text with a suite of 50+ integrated tools. Decode JWTs, test regex, transform data, and manage your clipboard without leaving the tab.
Everything runs 100% in your browser. Zero tracking. Zero accounts. Zero servers. Just pure, private utility.
Code snippets, API responses, log files, random JSON blobs—they don't belong in your project files, but you need a place to work with them. Scratch Tabs allows you to instantly compare, clean, transform, and validate that data before it moves to its final destination.
No registration required. Instant access.
Built by developers, for developers
It's for the data in transit—the JSON you just copied, the log you need to filter, the two code snippets you need to diff.
Stop polluting your editor with
Untitled-*
files. Give your temporary data a proper home where it can be
instantly formatted, analyzed and transformed.
