Frequently asked questions
What regex flavor does this tester use?
It uses JavaScript's built-in regular expression engine, since it runs entirely in your browser - syntax is broadly compatible with PCRE but has a few JavaScript-specific differences (e.g. lookbehind support varies by browser version).
Why does my pattern match in one tool but not another?
Different programming languages implement slightly different regex flavors (PCRE, POSIX, .NET, JavaScript) - a pattern that works in one may need small adjustments for another.
Is my test data uploaded anywhere?
No - matching happens entirely client-side in your browser; your pattern and test string are never sent to a server.
