Regex Tester
Test and validate regular expressions by entering a pattern, flags, and sample text.
The tester highlights matches, displays the number of hits, and shows captured groups
to help you understand how your regular expression behaves.
You can freely combine flags such as global, case-insensitive, or multiline, and instantly see the results reflected in the output.
Syntax errors are detected immediately and shown as clear error messages, making it easier to debug and refine complex patterns.
This tool is useful for developers, data analysts, and anyone working with text processing, log analysis, form validation, or search patterns.
All testing is performed locally in your browser, and no input text or patterns
are sent to any server, allowing safe and private experimentation.
