Regex Tester
Type a regular expression and some test text to see every match highlighted live, with its position in the text.
Pourquoi utiliser cet outil ?
Writing a regular expression by trial and error in your own code is slow. This tool lets you test a pattern against real text instantly, see exactly how many matches it finds and where, entirely in your browser.
Why it's free
A discreet ad banner covers hosting costs — that's the whole business model. No account to create, no usage limit, no paid tier unlocking the real result. Calculations run in your browser, so your numbers, dates and text never leave your device.
