Ask HN: Heroku equivalent for cheap intermittent jobs?

I'm running what's essentially a quote-of-the-day bot, which retrieves a text from a queue on a regular schedule, and submits it to another service over an HTTPS API.

Since my free Azure credits have expired, I'm looking for a cheap place to run a very small Python script intermittently, with access to some form of persistent storage.

My patience for being my own sysadmin is steadily decreasing, so I'd rather not run it at home or on a manually managed VPS if I can help it - ideally I'd like something like Azure's Container App Job system, but on a fixed monthly charge rather than a pay-as-you-go system.

Does such a service exist?
