About Regex Tools
Regular expressions are hard to read and easy to get wrong. Test yours against real sample text and see exactly what matches before it reaches production.
Every tool here runs client-side in your own browser. Nothing you paste is uploaded, so they are safe to use with work-in-progress code, client files and private content — and they keep working once the page has loaded, even offline.
