Regex Match Visualizer
Visualize regex matches with highlighted groups and real-time pattern testing.
Pattern token reference
Token hints are not a complete semantic explanation of nested expressions.
\b A word boundary
\w A word character (letter, digit, or underscore)
+ One or more of the preceding token
@ A literal "@" character
\w A word character (letter, digit, or underscore)
+ One or more of the preceding token
\. A literal "." character (escaped)
\w A word character (letter, digit, or underscore)
+ One or more of the preceding token
\b A word boundary
Highlighting matched text in a sample string shows what a pattern found, but it doesn't show how the pattern itself is actually structured, which groups nest inside which, where an alternation branches into separate options, a different question that matters once a pattern gets complicated enough that its own shape is hard to hold in your head just from reading the raw syntax. This tool visualizes a regex's matches with highlighted groups while testing in real time, making a pattern's internal structure, not just its matched output, easier to follow at a glance.

Useful for understanding how a complex pattern's groups and alternation actually nest together rather than just seeing what text it matched, following exactly which capture group corresponds to which highlighted piece of a match, or making sense of an already-written pattern's internal structure before modifying it.
