About This Tool
Regex Tester lets you write and test regular expressions with real-time match highlighting. See all matches, groups, and capture positions as you type. Supports all JavaScript regex flags: g, i, m, s, u, and y.
Match results show the matched text, its position in the string, and any named or numbered capture groups. Multiple matches are highlighted in different colors.
Built on the JavaScript native RegExp engine. Useful for validating email patterns, parsing log files, extracting data from structured text, or building input validation rules.
