Frequently asked questions

How is this different from regex101?

Regex101 requires an account to save patterns and runs server-side. Our tester runs entirely in your browser, needs no account, and is part of a full tool suite you can use offline.

Does this support PCRE or other flavours?

We use JavaScript's native RegExp engine. For PCRE-specific features, regex101 may be more suitable. For JavaScript regex work, our tool matches your runtime exactly.
