Customizable compute built
to optimize your CI/CD pipeline
Use resource classes to increase developer productivity and reduce build times
by
optimizing the compute power for your CI/CD jobs.
Boost productivity
Speed up software delivery pipelines so that developers can spend more time writing code and less time waiting for code to build.
Custom compute
Build, test, and deploy applications with unique system requirements without managing your own hardware.
Granular Optimization
Resource classes give DevOps teams full control over the compute allocated to each job so that pipelines run as efficiently as possible.
Available Resource Classes
Complex builds can be time-consuming. CircleCI offers powerful resource classes that speed up jobs and reduce developer wait time. Customize CPU, GPUs, and RAM by choosing one of our pre-configured resource classes to run your build.
Selecting Resource Classes
Easily run jobs on any of the available executors any time you need. Utilize multiple types and sizes in the same workflow.
Resource class availability varies by the type of plan you hold. See chart for distinction.
