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.
