Dagger is an automation engine that lets you define build, test, and deployment workflows as code, then execute them consistently whether running locally on your machine, in a CI/CD pipeline, or in the cloud. It uses containers and a GraphQL API to handle task caching and dependency management, making it useful for teams that want to standardize their DevOps processes across different environments without vendor lock-in. Developers use it to write reproducible automation workflows once and run them anywhere, reducing friction between local development and production deployments.
