"CircleCI is an excellent product and was the clear winner over the alternatives when I tried them all out: I was able to get a green build the fastest and hit the fewest bumps."

“There is a growing awareness within the company to introduce CI from the early stages of projects.”

“We had one teammate who was running Jenkins – logging in the morning, checking, breaking everything, and asking us to fix the issues he introduced. It was time-consuming for him and for at least one person on each specific team.”

"There are so many challenges in building working software within government that you deliver to the public in 6 months. CircleCI lets us focus on the things that matter."

"Fastlane is built around the principle of continuous deployment. Having a partner like CircleCI that is consistent and reliable enables us to not only deliver the best value to our customers, but deliver it with total confidence."

“We like to let machines do what they do best, leaving humans to do what they’re really good at.”

“CircleCI is both the fastest and the easiest CI I’ve used to date.”

“We use CircleCI to test all of the touchpoints between our platform and Drupal, for example, and create scripts that fire up the tests automatically.”

“CircleCI makes testing simple. It’s easier than any continuous integration tool I’ve used.”

“CircleCI multiplies the value that we get out of our tests, and it’s an important piece of a healthy software development process.”

“We love CircleCI’s responsiveness — there’s an awesome team behind the product!”

“We chose CircleCI primarily for its ability to automatically parallelize tests across many workers. Another primary factor is its cost structure. The cost structure enables us to optimize infrastructure costs by provisioning spot instances on Amazon Web Services, instead of on-demand or reserved instances, and we can scale our compute …
