Ask HN: What is the cheapest, easiest way to host a cronjob in 2022?

I thought this could start a good debate on the subject. Myself I have had to make a short running web-scraping job that, given a change in the site, sends a notifying email. This running once an hour.

It is 2022, so I had thought it would be tremendously easy and cheap, but it seems no solution is easily implemented.
