What are good options for configuring something somewhere to make an HTTP request to a specified URL on a schedule?

I've used cron on a VPS, GitHub scheduled actions, Val Town and Google Cloud Scheduler in the past

I'm looking for more options like that - specifically interested in cheap, reliable, easy to use and likely to stick around for a long time

@simon I use GitHub Actions for this, largely since it’s the most legible for my purposes - source-backed, documented, there’s a built-in UI, easily manually triggered (both locally and through the system itself).
