What is Semaphore?

Semaphore is a continuous integration and deployment platform that automates software delivery pipelines. It connects to your version control system (GitHub, GitLab, Bitbucket) to run tests, build applications, and deploy code automatically when you push changes. The platform emphasises real-time collaboration, allowing teams to see build status, logs, and deployment progress together. It's designed for development teams of any size who want to reduce manual work around testing and deployment, catch bugs earlier, and ship code more frequently.
