The regex editor, tester, and debugger in one

Regex is confusing. You copy/paste from Google or ChatGPT and pray it works. Half the time it breaks your code and you have no idea why.

So I made Regexr, a regular expression editor that shows you what your patterns match in real-time, and explains what each part does.

There are 3 ways to create patterns: AI-powered generation (describe what you want in plain English and get instant regex), visual builder (click components like LEGO blocks to build patterns), and ready-made patterns (choose from 50+ presets).

Test your patterns with live highlighting on real text, then export working code for 8+ programming languages.
