Dagger

Dagger provides a programmable CI/CD engine, enabling developers to define and execute their pipelines within containers. This approach allows for writing pipelines as code, utilizing the same programming language as the application itself. Developers can select their preferred SDK and begin coding immediately.

Dagger's execution model leverages standard OCI containers, offering several key advantages. These include instant local testing, ensuring rapid iteration and debugging. Portability is enhanced, as the same pipeline can seamlessly run across various environments, such as local machines, CI runners, dedicated servers, or any container hosting service. The system also provides superior caching capabilities, with every operation cached by default and consistent caching behavior across all environments. Furthermore, Dagger offers compatibility with the Docker ecosystem, allowing integration of any containerized tool into the pipeline. Finally, cross-language instrumentation enables teams to leverage each other's tools, regardless of the programming language used.
