FAQ
Which regex flavor does this use?+
JavaScript's RegExp engine (ECMAScript). Some features like lookbehinds require modern browsers.

g = global (all matches), i = case-insensitive, m = multiline (^/$ per line), s = dotAll (. matches newlines), u = unicode.
Is my input stored?+
No — everything runs locally in your browser.
