How many do you have? There's fixed costs and variable costs, after all. NixOS-configured systemd timers work great. Code them in bash, Go, Haskell, whatever.

If you like polyglot (mostly to leverage any community's open source apps), NixOS is the best. It isn't the cheapest or easiest for a single job. It's not hard to deploy to a random $5 VPS though (I use a Digital Ocean droplet). But once you have a box to deploy to, the incremental cost is as cheap as it gets.
