Lookaheads, Unicode property escapes, and backreference rules match what your browser supports in RegExp. A pattern that works in grep -P may fail here. Use this to debug code that will actually run in JS, not to prototype server-side Perl.
With the global flag, all matches are listed via matchAll. Without it, you get the first match and capture groups. Invalid patterns throw with the engine error message.
No replace or split UI, no regex cookbook code generation, and no protection against catastrophic backtracking — a pathological pattern can freeze the tab. Do not paste secrets you would not put in devtools.
JavaScript RegExp only — not PCRE/Python.
No replace/split helpers.
Catastrophic backtracking can hang the tab.
This engine is JavaScript RegExp. Features like (?P<name>) or \K are not available. Port the pattern to JS syntax.
Typical flags: g global, i ignore case, m multiline, s dotAll, u unicode, y sticky — combined in the flags field as in new RegExp(pattern, flags).
No. Matching runs locally.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
