About cron expressions
Compose standard five-field cron strings from inputs and presets. Copy the expression into crontab, containers, or CI schedules.
Why a visual builder?
Cron syntax is compact but easy to misread. Editing fields separately reduces mistakes when you are translating a human schedule into a machine expression.
Key features
- Five fields aligned with common Unix-style cron.
- Quick presets for frequent patterns.
- Live expression string with copy support.
- Runs locally in your browser.
How to use
- Set each field or pick a preset.
- Copy the generated expression.
- Paste into your scheduler and verify in a staging environment.
