131 CircleCI Testimonials

“We want to optimize and reduce the time it takes to run our builds and tests."

“We have the flexibility to quickly scale up and scale down."

“The previous CI/CD tool required manual deployments.”

“A lot of folks think it’s just content. But there’s a lot going on behind the scenes to get that text on the screen and deliver it to millions of people.”

“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.”

"We can save time by scaling the number of parallel jobs, and we can save costs with CircleCI’s pay-as-you-go solution.”

“Caching hastens our workflows because the Docker images from our research team are usually huge – about 10 gigabytes. We can quickly develop our CI pipeline because caching reduces the wait time from hours to minutes.”

“CircleCI is refreshingly simple and straightforward to get anything up and running.”

“It’s outdated, it’s been there for too long, and it’s lagging behind. But people still keep using it and stumbling on the same mistakes and problems and resource consumption.”

"We can still allow developers to do custom work if they want to, when they want to; developers are in complete control.”

“We became a complex landscape. It made sense to better integrate our teams to ensure we provide better customer solutions for their demanding and highly regulated financial markets.”

“We use a continuous iterative approach that focuses on collaboration, customer feedback, and small, rapid releases. We also train all team members in a variety of similar and equal skills by switching teams quarterly.”

"CircleCI’s default mode was a game changer for us."

"CircleCI is so far out in front; when you start out with CircleCI, you can skip talking about CI/CD platforms for years to come.”

"CircleCI is integral to our entire development process.”
