Bummer there's no free tier. I've been bashing my head against an intermittent CI failure problem on Github runners for probably a couple years now. I think it's related to the networking stack in their runner image and the fact that I'm using docker in docker to unit test a docker firewall. While I do appreciate that someone at Github did actually look at my issue, they totally missed the point. https://github.com/actions/runner-images/issues/11786

Are there any reasonable alternatives for a really tiny FOSS project?
