What is a regular expression?

A regular expression (regex) is a pattern used to match, search, and manipulate text. It's supported in virtually every programming language.

How do I test my regex?

Enter your regex pattern in the pattern field, add test text below, and the tool will highlight all matches in real-time. Flags like 'g' (global) and 'i' (case-insensitive) are supported.

Is my regex data safe?

Yes. All regex processing happens in your browser using JavaScript's built-in RegExp engine. No data is sent anywhere.
