Unfortunately the day has come. As a self-bootstrapped company Cirrus Labs can no longer provide unlimited usage of Cirrus CI for public repositories for free. We have to put a limit on the amount of compute resources that can be consumed for free each month by organizations and users. Starting September 1st 2023, there will be an upper monthly limit on free usage equal to 50 compute credits (which is equal to a little over 16,000 CPU-minutes for Linux tasks).
The reason for the change is that we want to continue being a profitable business and keep Cirrus CI running, but unfortunately we haven’t found a better solution for a couple of ongoing issues described below.
