The webhook scheduler
developers actually use.
Cronengine sends an HTTP request to any URL you configure, on whatever schedule you set. From every minute to once a year, automate your tasks without touching your server's crontab.

What is a webhook scheduler?
Your tasks, triggered on a schedule
A webhook scheduler is a service that calls an HTTP endpoint - a URL on your app, API, or any web service at a time you specify. You write the logic on your end; Cronengine handles the clock.
This pattern lets you trigger background tasks, batch processes, and automations without running a local cron daemon, maintaining a persistent worker process, or depending on cloud provider schedulers that lock you in.
Any URL that responds to an HTTP request can be scheduled - your own endpoints, third-party webhooks, Zapier hooks, or automation platforms.
Use cases
What developers use it for
If it has a URL, you can schedule it. Here are the most common tasks people automate with Cronengine.
Send invoices & reports
Trigger your invoice generation or report delivery endpoint on a schedule - every Monday morning, end of month, or at any interval that fits your billing cycle.
Sync products & inventory
Keep your e-commerce catalogue, stock levels, or pricing in sync with a supplier or warehouse system by hitting your sync endpoint every 15 minutes.
Clean up sessions & temp data
Purge expired sessions, soft-deleted records, temp files, or stale cache entries every night without running a persistent background worker.
Send newsletters & digests
Call your email dispatch endpoint on a fixed schedule - weekly digest every Friday morning, daily summary at 08:00, or a monthly newsletter on the first weekday.
Aggregate analytics & metrics
Trigger a data aggregation job to roll up raw events into daily or weekly summary tables, keeping your dashboards fast without heavy real-time queries.
Trigger database backups
Hit an endpoint that initiates a backup, snapshot, or export to object storage every hour or every night without relying on your hosting panel's built-in scheduler.
Replace WordPress WP-Cron
WP-Cron only fires when someone visits your site. Replace it with a real scheduler by disabling WP-Cron and hitting yoursite.com/wp-cron.php on a fixed schedule.
Process queued jobs
Kick off a queue worker that processes pending tasks, such as email sending, image resizing, or PDF generation, every minute without running a persistent daemon.
Poll external APIs
Pull data from an external service that doesn't support webhooks, such as stock prices, shipping status, weather, or CRM updates, and process it on your side on a schedule.

Who uses it
Built for everyone who builds for the web
Freelancers & indie devs
Automate client site maintenance, WP-Cron replacements, and background tasks across multiple projects, all from one dashboard.
SaaS teams
Replace homegrown schedulers with a reliable external service. Group jobs by environment with maps so staging and production never get confused.
E-commerce stores
Automate inventory syncs, order processing, abandoned cart emails, and daily sales reports without touching your hosting environment.
Digital agencies
Manage scheduled tasks for all your clients in one place. Each project gets its own map; each environment gets its own set of jobs.
What happens when a job fires
Cronengine fires an HTTP GET
The dispatcher sends a GET request to your URL from a fixed IP (45.9.188.216) so you can whitelist it on your firewall.
Your endpoint does its work
Your application receives the request, executes its logic, and returns an HTTP status code. Any response body is captured in full.
Run is logged & you're notified
Status, duration, and the full response body are stored. If the job fails, you get an email alert immediately, no polling required.
