Scheduled HTTP requests for your URLs and APIs
The cron scheduler lives at it3.site/cron alongside the rest of it3.site. Use one login to build crontab-style jobs, preview next run times in your timezone, send test requests, and keep a history of responses—ideal for lightweight uptime checks and small automation hooks.

Jobs are created inside the dashboard (new job form). Same session as the main site — no separate subdomain.
What you can do with this tool
Crontab-style scheduling
Use standard five-field expressions plus timezone context so you know exactly when the next execution lands.
HTTP methods and payloads
Call GET, POST, PUT, PATCH, or DELETE with custom headers, timeouts, and bodies when your endpoint needs them.
Test before you rely on it
Send a one-off test request from the UI to verify status codes and response shapes before saving the job.
History that stays readable
Keep recent runs and status codes in one place so you can spot failures without digging through server logs.
How it works
- Sign in on it3.site (or register) — your session works for /cron and the main app on the same domain.
- Open the dashboard and use “new job” to paste your URL, pick method, headers, and schedule.
- Preview upcoming runs, run a manual test, then save. Monitor results from the same dashboard.

Frequently asked questions
What is the Cron Job Scheduler at it3.site/cron?
It is a free companion tool from it3.site that runs scheduled HTTP requests (GET, POST, etc.) to URLs or APIs you choose. You define a crontab-style schedule, optional headers and body, and review run history from your dashboard.
Do I need a separate account for the cron tool?
No. You use the same it3.site login everywhere. After you sign in, open /cron/dashboard to manage jobs with the rest of the site on the same domain (so your session stays active).
Is this the same as Linux cron or cron-job.org?
The idea is similar—run tasks on a schedule—but this tool is focused on HTTP pings and simple API checks from it3.site’s infrastructure. It is meant for developers and marketers who already use it3.site and want lightweight scheduling without extra accounts.
How do I know my job will run on time?
The dashboard shows schedule previews based on your timezone and crontab expression. Execution also depends on the server scheduler calling the runner endpoint; ensure your hosting setup follows the deployment notes for the runner so due jobs are not skipped.
What URLs should I avoid calling?
Do not use the scheduler to attack third-party sites, scrape without permission, or violate our acceptable use policy. Only call endpoints you own or are authorized to hit, and respect rate limits.
Where can I get support?
Start with the FAQ on it3.site, the about page, and your dashboard. For policy questions, see the Terms of Service and Acceptable Use pages on it3.site.
