Schedule JavaScript automations that run on a timer — ping URLs, fetch data, send emails via Resend, create todos. Templates included, secrets stored securely.
CronJob lets you write real JavaScript with full fetch() access and run it on a recurring schedule. Pick a built-in template — Ping URL, Send Email, Fetch & Log, Create Todo — or write your own script from scratch. Jobs run server-side on Cloudflare Workers, so they execute even when your browser is closed.
API keys and secrets are encoded client-side and decoded only inside the execution sandbox. They never appear in logs, API responses, or network traffic.
Choose from built-in templates: Ping URL, Fetch & Log Data, Send Email (Resend), Reminder, Create Todo, or start with a Custom Script.
Schedule jobs hourly, daily at a specific time, weekly on a given day, or monthly. Plain English syntax, no cron expression knowledge needed.
API keys and secrets are base64-encoded client-side and decoded only inside the V8 execution sandbox. Keys never appear in logs or API responses.
View the console output of each run directly in the app. Errors, warnings, and log lines are captured and timestamped.
Run any job immediately from the detail panel without waiting for the schedule. Useful for testing new scripts.
Jobs run server-side on Cloudflare Workers via a cron trigger every minute. Scripts execute even when your browser is closed.
Most automation tools (Zapier, Make) cost $20–100/mo and lock you into their visual flow builders. CronJob lets you write real JavaScript with full fetch() access and run it on a schedule — included in the $1.99/mo Pro plan. Your scripts, your logic.
Included in Pro. $1.99/mo for all Pro plugins.
