Regex, cron, semver, and glob — paste, run, see the answer. Computed entirely in your browser.
- Regex tester
Test a regular expression against your own text — the browser’s own engine, in a disposable worker.
- Cron explainer
Explain a cron schedule in plain English and list its next fire times, dialect and timezone explicit.
- Semver compare
Sort versions, compare two, and match ranges — strict SemVer 2.0.0, coercion shown separately.
- Glob tester
Test glob patterns against a list of paths — picomatch in a bounded worker, dialect explicit.
