Github runners are slow. We're using WarpBuild and they are still cheaper per-minute, even with all the changes Github has made. Then there's the fact that the machines are faster, so we are using fewer minutes.
There are multiple competitors in this space. If you are (or were) paying for Github runners for any reason, you really shouldn't be.
We also use WarpBuild and very happy with the performance gain. This changes nothing except maybe it should signal to WarpBuild to start supporting other providers than Github. We are clearly entering the enshitiffication phase of Github.
Thanks for the WarpBuild love!
Performance is the primary lever to pay less $0.002/min self hosting tax and we strive to provide the best performance runners.
