About dagger
Dagger is an open source automation engine for software delivery, written in Go and released under the Apache 2.0 license. It builds, tests and ships any codebase, and it runs locally, inside a CI server, or directly in the cloud. The project lives in the cloud infrastructure and CI/CD ecosystem, where it occupies the space normally filled by shell scripts and proprietary pipeline YAML. It has been developed for roughly seven years and carries a substantial community footprint, with more than sixteen thousand stars and over nine hundred forks on GitHub.
