Dagger vs semaphore

Dagger is an automation engine designed to streamline the process of building, testing, and shipping codebases. It can run locally, in CI, or directly in the cloud, making it a versatile tool for developers and teams. Dagger aims to simplify the development workflow by automating repetitive tasks and providing a consistent environment for testing and deployment.
