Dagger

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.

Dagger publishes 5 APIs on the APIs.io network, including Graph QL API, and 4 more. Tagged areas include Build Automation, BuildKit, CI/CD, Containers, and DAG.

The Dagger catalog on APIs.io includes 1 JSON-LD context.

Dagger’s developer surface includes authentication, documentation, getting-started guide, engineering blog, pricing, signup flow, YouTube channel, and 42 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 75 points between them, because both conditional facets apply and carry 25 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dagger: open an issue to ask a question, or submit a pull request to add artifacts.
