Regex Tester

Test regex patterns with live match highlighting.

Getting a reliable result

Start with a short valid snippet and inspect the formatted or transformed output before copying it into your project.

Limitations to check

Formatting does not prove that a program is correct or secure. Run the result through your project's compiler and tests.
