We have been using travisci pro for years, and pay a whopping 5k a year for 10 concurrent builds. The cost or amount of builds is not really the issue though. It is the power of the underlying machines. Our builds flows are optimised to the max, but we have for example a 10 minute create-react-app build (webpack) which cannot be sped up in any way, except bigger CPU’s. 2 min on my top spec mbp vs 12 minutes on travis. But they do not have plans with faster machines, so not really an option. How are you all handling these kinds of problems?
