December 2024

Pushover.net integration

You can receive cron notifications on your Pushover.net devices. Copy your user key from your Pushover account, then add it on the Channels page.

Random delay

You can now add a random delay when adding/editing cronjobs. Click the Expression button and enter a delay time in minutes.

For example, you schedule your cronjob with cron expression 45 6 * * * and a random delay of 20 minutes. Your cronjob will run once a day from 6:45 to 7:05.

Schedule a maintenance

To pause cronjobs during a planned outage, you can schedule a maintenance. Your cronjobs won’t run during a scheduled maintenance period. Queued cron executions will be rescheduled to run after maintenance ended.

November 2024

Filter cronjobs by priority

You can now filter cronjobs by priority. To do so, click on the Filter icon on the search form to select the desired priority.

Cronjob vs group priority

A cronjob can have a different priority than its group priority. Changing a group priority will only raise all its cronjobs to the same priority.

Old API endpoint deprecated

FastCron will stop proxying https://www.fastcron.com/api/ to https://app.fastcronjob.com/api/v1/. Please update your endpoint URL in your config as soon as possible.

October 2024

Clean up

  • Old webhook URLs have been moved to the Notification channels.
  • The allowed groups of team members have been removed. They will see all cronjobs with the same or lower priority.
  • Group notification recipients have been removed. They will receive cron notifications from all cronjobs with the same or lower priority.
  • Stopped one-time cronjobs will be removed after 3 days.
  • You won’t be able to run disabled cronjobs using the API function cron_run.
  • Exports have priority too. Team members can view, download, delete, and import files with the same or lower priority.
  • Fixed: use Rn in the hour field in your cron expressions to select n random values.

POST data/payload validation

FastCron will now validate postData and payload. The POST data must be

  • Valid query string in the format name=value&name2=value2. No newlines are allowed.
  • If the postData/payload has newlines or starts with {, it must be valid JSON string.

Hide archived cronjobs

FastCron will archive disabled cronjobs after 180 days, and won’t show them on the dashboard by default. You can see them when using the search form. To see all archived cronjobs, select Archived status on the search form.

Remove inactive account

FastCron will remove free accounts with no active cronjobs and no activity after 180 days. Due to the high rate of invalid email addresses and bounced messages, FastCron won’t send any notifications before removal.

Notify when output contains a word

You can receive cron notifications (from emails and all other channels) when your cronjob output does/doesn’t contain a word. To enable it, click Edit cronjob. In the section Notifications, enter the desired word into Notify if contains.

September 2024

Variables

You can now add variables on the Environment variables page.

Use __variable_name__ in the cronjob URL, POST data, or payload, and it will be replaced with the variable value when the cronjob priority is the same or higher than the variable priority.

It’s useful for secret key/token, API/authorization token, or configuration values.

Use it when:

  • you don’t want to share secrets with your team members.
  • you want to change it once and apply to all cronjobs.

Team members

Members and Viewers now can see other team members. All team members can choose to start/stop receiving cron notifications from the team account on the Members page.

Priority level

You can now set priority level for your cronjobs, groups, channels, variables, and team members.

Free WordPress plugin

You can now install and activate our official WordPress plugin here. It will create a free cronjob running every 5 minutes to your wp-cron.php. Completely free, no registration required, just activate and done.

Jira integration

FastCron now supports Jira integration. FastCron will trigger your automation rule with incoming webhook trigger. You can then add an action to process the notifications: send emails to team, create a new issue, or comment on an existing issue.

Search in cron_logs and cron_failures

You can now add keyword to cron_logs and cron_failures function to search in logs output, error message, and execution time (Unix timestamp).

August 2024

Disabled cronjobs won’t run

In 2 months (after October 20, 2024), you can no longer use cron_run to run disabled cronjobs. You need to edit the disabled cronjobs, select When to call: Manual, then Save and Enable them.

Cron expression manual

You can now create cronjob to run manually by selecting When to call: Manual or set the expression to manual. Use it to:

  • Run cronjob manually only when necessary
  • Create an endpoint URL for one-time executions
  • Create chained cronjobs: run this cronjob only after another cronjob complete (edit cronjob > Notifications, at Run cronjob, select the manual cronjob).

cron_run with time and payload

You can now set both time and payload when calling cron_run function. It’s great for running one-time cronjobs programmatically.

This is the recommended way to run one-time cronjobs.

Note: In 3 months (November 18, 2024), a one-time cronjob will count as one regular cronjob. Please update your script to use cron_run instead of cron_add before that day.

cron_next API function

A new API function has been added. cron_next will return an array of next execution times.

Telegram integration

You can now receive a Telegram message from @FastCronBot when cronjobs fail/succeed.

SSL certificate expiry dates

FastCron will monitor your SSL certificate expiry dates for your active cronjobs. You can view the SSL cert expiry dates on the Hosts page.

July 2024

Unlimited team members

You can now add unlimited team members to your account, even in the free plan!

Ignore HTTP status is removed

Your cronjob URLs should return HTTP status code 2xx. Otherwise, they will be marked as failed and disabled after a number of consecutive failures.

Previously, you can choose to ignore all HTTP status codes (3xx, 4xx, 5xx). The option has been removed. You can choose to ignore one HTTP status code at a time on the cron logs page or in a failure notification email.

Cronjob statistics and monthly report

FastCron has started collecting cronjob statistics (total runs/failures, average execution times, total 4xx/5xx responses) since July 15. You can choose to receive monthly reports on your profile page.

June 2024

Notification channels

You can now add account-level notification channels including Slack, Zenduty, Discord, Teams, and webhook (JSON payload). Once added, all failure/success notifications will be sent to your channel(s).

You can disable or delete a channel in case you don’t want to receive further notifications.

FastCron will show the last error message when failing to send notifications to your channel. We will automatically disable your channel after 5 consecutive failures.

Removed daily execution limits

The base cronjob interval is 1 minute. You can create cronjobs to run up to every 5 seconds, but they will count as 12 cronjobs. You can create up to 1,440x one-time cronjobs.

Changed retrying failed cronjobs

Failed then disabled cronjobs will no longer be retried and enabled.

  • The default failure threshold is 20 consecutive failures.
  • You can update it at the section Failures, retry, and repeat.
  • When your cronjob fails half of the threshold, we will back off:
    • 1 day if your cronjob runs 4 times a day or less
    • 3 hours if your cronjob runs 24 times a day or less
    • 1 hour otherwise
  • When the cronjob exceeds the failure threshold, it will be disabled.
  • You will receive a cron notification (via email, Slack, or webhook) when that happened.

Removed old servers

3 old servers are scheduled to removed:

  • scj-app01 removed on June 11, 2024
  • scj-app02 removed on June 18, 2024
  • scj-app03 removed on June 25, 2024
  • scj-app04 removed on July 2, 2024

Please ensure that we can reach your cronjob URLs with the new IP addresses by whitelisting our IP addresses.

You can now run your cronjob at a specific time using cron_run with time parameter.
