Who runs Cron Hut

Cron Hut is an independent project run by a solo developer. The goal is simple: fast, uncluttered tools that respect your privacy, open instantly and never ask you to register.

Why we built it

One misplaced field in a cron expression can make a backup run every minute instead of once a day. Cron Hut explains each expression in plain English and previews the upcoming run times, so you can verify a schedule before deploying it to a server or CI pipeline.
