“Switching to CircleCI has allowed our engineers to build and release mobile and web projects with far greater simplicity, speed and performance.”
“CircleCI is one of those tools that silently chugs along in your stack doing some serious heavy-lifting. That’s what you want in your unit testing infrastructure - something to get the job done with zero maintenance overhead.”
“With CircleCI, we have probably saved $75-300K in maintenance on Jenkins. We’ve also had fewer headaches and shipping is easy.”
