Nah, Github Actions is actually amazing, and has been rock solid for me.
For someone who's not a pro in using CIs, it's been much easier to use than CircleCI. I never have to spend more than 20 or 30 minutes fiddling with Actions to make it actually work.
This for me is the biggest contribution to open source: normal people like me (who don't want to get too familiar with proprietary or overengineered CI tech) will be able to have CIs for pretty much ALL their projects.
I can’t speak for actions but you seem extremely biased for some reason. It would take you less time than it took to write this post than to learn circleci. Much less than 20-30 mins.
The initial capabilities look similar and circle really needs a competitor with how flaky their service has recently been.
