Dagger.io is an open-source CI/CD engine that lets teams define pipelines as code using familiar SDKs and containerized steps. It emphasizes reproducibility, portability across runners, and local-to-CI execution. The platform also offers Dagger Cloud for observability, caching, and team workflows.
The open-source Dagger engine is free to use and self-host under its permissive license. Dagger Cloud typically offers a free tier for limited usage, paid team plans for additional runs/seats/observability, and custom enterprise pricing for scale, SSO, and support; check current plan limits because usage-based pricing can change.
Open Source
Dagger.io’s biggest strength is treating CI/CD as real code while keeping builds reproducible and portable. It is especially useful for teams frustrated with brittle YAML pipelines and for organizations that want consistent local-to-CI behavior. The main trade-offs are a learning curve and a smaller ecosystem than incumbent CI tools. Use it if you value maintainable pipelines, container-native workflows, and strong reproducibility.
