Regex Tester
Test and debug regular expressions with live matches.
Regular expressions are powerful but unforgiving — a stray character changes everything. Type your pattern and some sample text and this tester highlights every match as you go, so you can refine the expression by sight instead of by guesswork.
Build patterns with confidence
- See matches and capture groups update live as you edit the pattern.
- Toggle flags like global, case-insensitive and multiline.
- Prototype validation for emails, phone numbers or slugs before wiring it into code.
Once a pattern behaves the way you want here, drop it straight into JavaScript, PHP or your editor's find-and-replace.
