In their own words
Dagger
Dagger is a software stack for continuous integration built around an API, executable code, and a portable DAG execution engine. Pipeline logic can run locally or in Dagger Cloud, with automatic caching and end-to-end tracing. Cloud Checks connect a GitHub repository to Dagger Cloud and run checks on Cloud Engines after events such as pushes or pull requests, without a CI workflow file. Official modules cover testing, linting, formatting, type checking, browser tests, and Helm chart validation, and can be extended in a user's preferred language. The CLI has installation instructions for macOS, Linux, and Windows, and the documentation includes a self-hosting guide. Individual is free and allows one user, 1,000,000 monthly events, one month of run history, and community support. Team costs $50 a month after a two-week trial, for up to 10 users, 10,000,000 monthly events, one year of run history, and email support. Enterprise pricing is custom; SSO and managed single-tenant deployment are contact items. The site links to security and compliance information.
