Is there a cool lightweight alternative to cron for (at least) a single host?

To illustrate what I am looking for, I often end up using supervisord [0] (but I also like immortal [1]) for process control when not on a systemd enabled system. In my experience they are reliable, lightweight and a pleasure to work with.

I am looking for something similar for scheduled jobs.

Supercronic: https://github.com/aptible/supercronic

Designed to run in a container, but should equally well work on a single host. However, no option for "high availability" running, where multiple hosts coordinate.

Take a look at this comment for some options: https://news.ycombinator.com/item?id=44752548
