Is the regex generator free to use?

Sign up free to use it — the Free plan includes a monthly word allowance, and paid plans unlock more.

How do I describe the pattern I need?

Plain English plus examples — "match dates like 2026-07-28 but not 28/07/2026" — and it returns the expression with an explanation of each part.

JavaScript, Python, PCRE, Go and more — dialects differ (lookbehind, named groups), so say where it will run.

Yes — paste any pattern and get a readable breakdown, which beats squinting at nested groups.
