I’m donating a shy of 20€ per month to services automatically on Liberapay/Opencollective as long as I can. I do /try/ to give back on the projects that I use a lot in either my time and effort (IE: sitting in their IRC channels helping people for example), or a monetary donation.
It’s not much, and I hope these open source projects never become something that depend on money and donations, but there are always cost to running services online.

I must mention this FOSS app! https://github.com/danilkinkin/buckwheat
I use this to track my monthly spend with my cards that I manually swipe at stores. This is the only budgeting app that has stuck with me for quite some time.
