This tool runs entirely in your browser and uses JavaScript's standard regular expression engine (ECMAScript); for other languages (PCRE in PHP/Python, etc.) some syntax may differ slightly. The "Explain pattern" section is a rule-based analysis of your regex's structure, not an actual execution of it.
