Visually build, test, and debug Regular Expressions in real-time with multi-language code snippets.
const regex = /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g;
const matches = text.match(regex);import re
pattern = re.compile(r'[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}')
matches = pattern.findall(text)$pattern = '/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g';
preg_match_all($pattern, $text, $matches);Regular expressions (RegEx) are powerful search patterns used for string matching and manipulation. The RegEx Rx Visual Builder allows you to write, test, and debug complex expressions against live text. With real-time visual highlighting and dynamic code snippet generation, mastering regex has never been easier.
The live test area evaluates expressions using the native JavaScript (V8) RegExp engine embedded in your browser. However, we provide integration snippets for Python and PHP to ease cross-language transitions.
Yes, capturing groups are fully supported by the engine, though the visual highlighter currently focuses on highlighting the entire matched string (Group 0) in the test area.
