Scheduler
The scheduler allows you to run apps on a pre-defined schedule. You will find it in Deploy > Set (it's green when active, gray otherwise):
You can schedule your app to run as often as you need, with a minimum interval of 5 minutes:
To set it up, perform a test run to verify that your code performs as expected and it fits in the allowed memory.
Besides confirming that the actions you were expecting took place, you can inspect the variables created / flow of your program in the Test Run:
The code will run in a headless browser in the cloud.
There is no end-user hence only compute-only modules will be executed (when developing, it's fine do have a page at the end that displays the results of the operation).
