RegexRay lets you search pages with real regular expressions and see results light up in place. Open the popup, type your pattern, choose flags like case-insensitive or multiline, and press Highlight. Matches are wrapped on the page so you can scroll and review them in context, then clear everything with one click. You can customize the highlight color, outline color, and a safe match cap to keep pages responsive. The extension injects its script only when you use it, stores your preferences locally, and never sends page content anywhere. It’s a quick way to spot IDs, emails, numbers, or any custom pattern without leaving the site you’re reading.
