I've added the instruction to set up Slack's incoming webhook on the Slack page, as well as fixed the Slack message to follow their markdown style.

The fail notification message should display correctly now.

The legacy team account


I've found and fixed a bug that updated your account's member limit incorrectly.

It occurred in the legacy accounts with the team option (e.g. Platinum team, Diamond team). The affected accounts were already updated.

If you have a legacy team account and see a member limit of 1, please let me know and I'll check it.

Unlimited plan


Update: The unlimited plan is now Business Unlimited.

You can now visit the Billing page and upgrade your account to the Unlimited plan at $250/month.

It has all the benefits of the Business plan. It has no limit on daily executions, recurring cronjobs, and team users.

Referral program update


Referral code is now available to both free and premium users.

Free users will be renewed for one month each time a new user signs up using their referral link.

The referral URL has been updated to use the r instead of the ref parameter.

The referrer will get a bonus of 20% from payments in the first year forever. The bonus will be listed on the Billing page. It will be used to renew your account immediately.

Free users who received the bonus will be renewed as if their account is at $12/year. For example, if you refer a customer who pays $25/month, you'll get a $5 bonus each month, which will renew your free account for 5 months.

Viewer / Read-only team member


You can now invite/add a team member with a Viewer role.


Viewers have read-only access. They can view cronjobs, but can NOT edit/delete/disable/run them.

Enable login throttling


A common brute-force attack against web applications consists of an attacker submitting a login form many times with the hope of eventually guessing the password of some user account.

One of the best countermeasures to these attacks is called "login throttling", which denies a user from attempting logins after a certain number of failed attempts.

From now on, FastCron allows only 5 login attempts per minute.

8w · 619

Run another cronjob after execution


You can now run another cronjob after a cronjob's successful execution. You should also disable the target cronjob if you want it to completely depend on the source cronjob.

This will double the daily execution count in the source cronjob. The feature is available in the premium plans.


8w · 622

Downgrade to free

Your account will be automatically downgraded to free 1 month after its expiration.

You can also choose to downgrade your account when it expires or has less than 7 days remaining.

Please note that free account requires monthly renewal by logging in with your Google account.
