Crontab Builder
Builds a crontab expression from friendly dropdowns and checkboxes — every N minutes, specific hours, weekday and month checkboxes — with one-click presets, a live preview of the next runs labelled with your timezone, and exports as a crontab line, systemd timer sketch or CI YAML. Paste an existing expression to load it into the controls.
Runs 100% in your browser — nothing you paste leaves your device.
