Regex101 / Regexr / Debuggex are EXPLAINER tools - you write the regex, they explain it. Free.ai is a GENERATOR - you describe what you need in English, it writes the regex. Use Free.ai for the first draft, then paste into Regex101 to test against your live data. Combined workflow saves hours over hand-writing regexes from a cheat sheet.

PCRE (default in PHP, Perl, most modern Linux tools). JavaScript (browser + Node, no lookbehind in Safari ≤16.3). Python re (closest to PCRE, no possessive quantifiers). Go regexp (RE2 - no backreferences, no lookarounds, but linear-time guaranteed safe). POSIX BRE/ERE (grep, sed without -E). Pick the one your target language uses - features like lookbehind / possessive quantifiers / named groups don't port across all flavors.

Honest answer: no regex matches every real-world input perfectly. Email validation alone has a 6,425-character "RFC 5322 compliant" regex nobody actually uses. Free.ai targets the 99% case for the use you describe and warns about known edge cases in the explanation (e.g., "this matches example.co.uk but not example.museum"). Always test against real data before shipping to production.

The model is instructed to avoid nested quantifiers like `(.+)+` that cause ReDoS. For Go (RE2) the engine guarantees linear time so this is impossible by construction. For PCRE/JS/Python, always test long inputs after - paste into Regex101 with a 10,000-char string and watch the steps counter.

Yes - paste a regex and ask "convert this Python regex to Go RE2". The model rewrites it using only the target flavor's supported features and warns when a feature has no equivalent (e.g., backreferences when going Python → Go).
