About Semaphore

Semaphore is a cloud-based Continuous Integration and Delivery (CI) platform that's fast, easy to use, and incredibly scalable.

What is CI/CD?​

Continuous Integration (CI) is an automated process of regularly merging code changes, running tests, and providing rapid feedback to developers.

CI enables developers to frequently merge code changes, automatically test them, and detect integration issues early, leading to faster development cycles and higher-quality software.

CI Workflow

Continuous Delivery and Continuous Deployment extend this process by providing a package you can release and deploy to the world. The whole thing is automated and can be set up to not need human intervention. No more stressing over deployment or releases!

CD Workflow
