Disclosure

Transparency about links and funding, per FTC guidance.

cronwell is free. Some outbound links — for example to cron- or uptime-monitoring services — may be affiliate links: if you sign up through them we may earn a commission at no extra cost to you. Paid links are marked rel="sponsored nofollow".

We only link to tools we’d actually use, and a commission never changes what we recommend or what the tool reports. The explanations and translations are computed purely from the expression you enter.

cronwell runs entirely in your browser and keeps no logs of the expressions you check.
