Build and debug regular expressions interactively. Toggle flags (g, i, m, s, u, y), view all matches with positions, inspect capture groups, and try replacements live. Great for learning regex or stress-testing complex patterns before shipping.

This tool runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
JavaScript ECMAScript regex - the same engine used in Chrome, Firefox, Safari, and Node.js. Look-behinds and named groups are supported.
The global flag finds all matches in the string instead of stopping at the first. Without it, replace() only swaps the first match.
Most often: forgetting to escape special characters (. + * ? ( ) [ ] { } | \), or missing the right flag (e.g. 'i' for case-insensitive).
