Cron job questions
What is an online cron job?
An online cron job is a scheduled task that a web service runs for you: FastCron calls your URL on a fixed schedule, so you do not need server crontab access.
Can I run a cron job every second?
Yes. FastCron runs cron jobs as often as every 2 seconds on the Pro and Business packages. Starter runs jobs every 10, 20 or 30 seconds or every minute.
How is FastCron different from hosting cron?
Hosting cron usually stops at one run per minute and gives no logs. FastCron has an always-on worker with no drift, live logs, failure alerts and an API.
Do my cron jobs keep running if my site is slow?
Yes. Each run has its own timeout and is logged with the status code and response time, and you get an alert when a job keeps failing.
