Regex Tester
Test regular expressions in real time. See highlighted matches and captured groups.
How to use?
Paste your regular expression in one field and the test text in the other. As you type, the matches get highlighted. To fine-tune the result, lean on the flags. The g flag finds every occurrence (global), i ignores upper and lower case (case-insensitive), and m treats each line on its own (multiline).

Regular expressions are powerful, yet notoriously hard to get right the first time. This tester makes the process visual. You write the pattern on one side, paste the test text on the other, and see at once which parts match, highlighted right in the content.
Captured groups show up separately, which helps you understand exactly what each part of the expression is grabbing. It makes all the difference when you're extracting data, validating formats or building a replacement. Changed the pattern? The result updates in real time, so you keep refining until you get there.
It all happens in the browser, with no text leaving your machine. A safe, quick way to work the kinks out of a regex before you drop it into your code.
