Cron Builder Visual
Pick cron fields and build a cron expression without memorizing syntax.
Build cron without memorizing it
Cron syntax is compact and easy to get wrong, especially the day-of-week and step fields. This visual builder lets you pick the schedule from plain controls — minute, hour, day, month, weekday — and assembles the correct five-field expression for you.
Building it visually removes the guesswork and the “does this run every minute or once a day?” anxiety. Set the fields, read the resulting expression, and copy it into your crontab, scheduler, or CI config with confidence.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
