# Dagger

**APIs profiled:** 5

Dagger is an open-source programmable CI/CD engine that runs pipelines in containers using a unified, introspectable GraphQL API. Pipelines are written as code in the developer's preferred language (Go, Python, TypeScript, PHP, Java, .NET, Elixir, or Rust) using Dagger SDKs and packaged as Dagger Modules that can be published to the Daggerverse module index. The Dagger Engine exposes Container, Directory, File, Secret, and CacheVolume as first-class GraphQL types backed by a content-addressed store, enabling deterministic builds and aggressive caching. Dagger Cloud provides the hosted control plane for pipeline traces, checks, and module observability. Dagger does not expose a public REST API; clients connect to a per-session Dagger Engine GraphQL endpoint and the optional Dagger Cloud Web UI.
