Self-Hosted Infrastructure

Yes! - We currently offer the following:

• CircleCI Server , a modern continuous integration and continuous delivery (CI/CD) platform installable inside your private cloud or data center. 
  
• CircleCI Runner enables you to use your own infrastructure for running jobs. This means you will be able to build and test on a wider variety of architectures, as well as providing you with additional control over the environment.
