What is a Regular Expression Tester?
A Regular Expression (RegEx) Tester is a developer tool that allows you to write regex patterns and test them against sample text strings in real-time. It helps you verify that your patterns match exactly what you intend, highlighting matches and extracting capture groups.
Features of our Regex Tester
- Real-time matching: See matches as you type.
- Capture groups: Easily view the contents of extracted groups.
- Flag support: Toggle global (g), case-insensitive (i), and multiline (m) flags.
- 100% Client-side: Your patterns and text are never sent to a server.
Common Regex Patterns
Here are a few common patterns you can test:
