Dagger
Dagger is a programmable CI/CD engine that allows developers to define their build, test, and deployment pipelines as code using a standard programming language like Go, Python, or TypeScript. It runs pipelines as standard OCI containers, providing portability across different environments and execution engines. This approach enables teams to create reusable, testable, and composable pipeline components that can be shared and versioned.
Developers should use Dagger when they need to create complex, maintainable CI/CD pipelines that can run consistently across local machines, CI runners, and cloud environments. It's particularly valuable for teams building microservices or monorepos where pipeline logic needs to be shared and tested like application code. Dagger eliminates the vendor lock-in of platform-specific CI/CD tools by using standard containers and programming languages.
