Wherever code lives,
build with the best
Teams that use GitHub, GitLab SaaS, and Bitbucket for source control rely on CircleCI to build, test, and deploy.
The speed, flexibility, and security you need
to ensure quality code delivery with confidence.
Speed
Faster builds mean delivering ideas as quickly as you can think of them. CircleCI consistently beats leading competitors in speed tests. Fine-tune your pipelines with caching, concurrency, test splitting, and more to increase your team’s rate of quality software delivery.
Resource classes

with diverse toolchains
“CircleCI is one of those tools that silently chugs along in your stack doing some serious heavy-lifting while staying out of your way. That’s what you want in your unit testing infrastructure - something to get the job done with zero maintenance overhead.”
“One of the best assets we have as a company is the smartest engineers we can find. Rather than provide slow or cumbersome tools, we want to provide self-service workflows for our engineers who can use them on their own time, in their own way. That’s why we have moved over to CircleCI.”
“Switching to CircleCI has allowed our engineers to build and release mobile and web projects with far greater simplicity, speed and performance.”
