Regex tester 🔎

Write a pattern, flip a few flags, and throw some text at it. Matches light up where they land, the groups spill out into a little table, and you can rehearse a replace before you commit. (now you have two problems. classic.)

It all runs here in the page, so your secrets stay your secrets. (the regex still judges them.)
