131 CircleCI Testimonials

“CircleCI is the hub, and the brain of our global automation.”

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

“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 up and down in response to demand. CircleCI’s robust API is also a plus, and has enabled us to implement time saving features--such as automatic bisect and time travel builds--which benefit the entire development team.”

“We can move and react faster with CircleCI and AWS, and help our customers transform their businesses.”

“CI/CD is critical for success for all companies, but there are a lot of ways to do it. CircleCI allows us to easily and quickly get projects onboarded and connect them with other parts of the tech stack.”

"Our engineers couldn’t imagine living without test splitting – they get test feedback in about 10 minutes.”

“CircleCI is integral to what we do here,” says Nick Iovino, Infrastructure Engineer at AdWerx. “It makes everything stress-free. We know that if something goes wrong, it’s going to be pretty easy to revert or remediate. We know that if we have downtime, it’s going to be pretty short – and we can keep on delivering.”

“Our approach was very much one size fits all. We were happy with any solution that did automated and fast builds.”

"Now that we’re a mid-size company, I don’t foresee us changing anything for the next few years.”

“The Next Domestic Passenger Project was launched and ANA is developing a system as a transformation support partner for ANA Group’s existing and new businesses.”

“Our company handles both front-end and back-end system development. We felt that the ability to build an environment that matches the characteristics of each system was a good fit for our business.”

“There are many different environments we run tests in. To have the confidence that all the pieces are functioning takes a lot of dev hours.”

“With 17 engineers, everyone is touching the same codebase."

“We chose CircleCI because it was easy to set up and gave good visibility to the whole team about the state of our tests. It worked out of the box with pre-built images that supported most of our system components. We were able to easily configure specific Docker images for parts that needed more customization.”

“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.”
