Regex Tester

Our Regex Tester provides a powerful yet intuitive interface for testing and debugging regular expressions. With real-time pattern matching, you can instantly see how your regex performs against your test strings as you type.

The tool supports all standard regex flags including global (g), case-insensitive (i), multiline (m), and dotall (s) modes. View all matches with their capture groups displayed in a clear, organized format. The match highlighting feature visually shows exactly which parts of your text are being matched.

Speed up your workflow with our quick-insert feature for common patterns like email addresses, URLs, phone numbers, dates, and more. Invalid regex patterns are handled gracefully with clear error messages to help you debug syntax issues. Copy your regex to the clipboard with a single click.
