Purpose: The tool lets users test, highlight, and learn regular expressions.
Live matching: It highlights matches in sample text and lists capture groups as the pattern is tested.
Pattern explanations: It explains common metacharacters, quantifiers, groups, and character classes in plain English, token by token.
Cheat sheet: A built-in cheat sheet gives meanings and examples for common regex symbols.
Flags: The global flag is always on, and users can toggle ignore-case, multiline, and dotall flags.
Regex engine: Patterns run in the browser using JavaScript’s built-in regular-expression engine.
Compatibility limit: The maker advises testing patterns in their target language because JavaScript, PCRE, Python, and Go differ in some regex behavior.
Explanation limit: The pattern breakdown is a learning aid and may label extremely exotic constructs generically.
Privacy: The maker says the tester runs entirely in the browser and does not upload or send entered text to a server.
Cost and account: The maker says everything on the site is free and requires no account.
Support: Users can email the two-person team with questions, feedback, suggestions, or bug reports; replies usually take a day or two.
Security: The maker says the site is served over encrypted HTTPS and limits risk by not collecting or storing personal data on its own systems.
