Frequently asked questions
Which regex flavour is this?
The JavaScript (ECMAScript) flavour built into your browser, so results match what JavaScript code will do.
Why does my pattern freeze the page?
Patterns with nested repetition can backtrack catastrophically on some inputs. Simplify the pattern or shorten the text.
Is my text uploaded?
No. Matching runs locally in your browser.
