What is Dagger?
Dagger is a programmable CI/CD engine that runs your pipelines in containers.
Develop your CI/CD pipelines as code, in the same programming language as your application.
Dagger executes your pipelines entirely as standard OCI containers. This has several benefits:
- Instant local testing
- Portability: the same pipeline can run on your local machine, a CI runner, a dedicated server, or any container hosting service.
- Superior caching: every operation is cached by default, and caching works the same everywhere
- Compatibility with the Docker ecosystem: if it runs in a container, you can add it to your pipeline.
- Cross-language instrumentation: teams can use each other’s tools without learning each other’s language.
Dagger may be a good fit if you are…
- A developer wishing your CI pipelines were code instead of YAML
- Your team’s “designated devops person”, hoping to replace a pile of artisanal scripts with something more powerful
- A platform engineer writing custom tooling, to unify continuous delivery across organizational silos
- A cloud-native developer advocate or solutions engineer looking to demonstrate a complex integration on short notice
