The continuous integration platform preferred by over 1 million engineers
Take control of the change
happening all around you
As soon as you think it, you can deliver it. Your developers’ time is too important to waste. No other CI/CD platform takes performance as seriously as we do. Your pipelines should accelerate your business, not slow you down.
The foundation for delivery at scale
Your CI/CD process is the heartbeat of your engineering organization. With CircleCI, teams are never limited in their ability to grow and innovate. Our experts are here to guide and support you every step of the way.
Confidence in every commit
Take control of your code and manage every source of change. CircleCI means change validation, at every step. Trust that you can release updates right when your customers need them, with the certainty they’ll work every time.
Your toolchain, your choice
CircleCI connects with services you already use like AWS, Slack, and Atlassian. Build on GitLab SaaS, GitHub, and Bitbucket.
Compliance and authorizations
We partner with the top security organizations to ensure
that your projects are built, deployed, and maintained securely.
“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.”
“Our time is money. Investing in CircleCI gives us time for more important projects.”
