Trunk

Trunk builds developer experience and CI reliability tooling. Its platform spans Code Quality (a meta-linter and static analysis manager driven by the trunk CLI), a flake-aware parallel Merge Queue, and Flaky Tests detection / CI Analytics. Test results are uploaded from CI via the Trunk Analytics CLI / GitHub Action, and an HTTP REST API at api.trunk.io exposes Flaky Tests and Merge Queue control plus Svix-powered outbound webhooks. Trunk is a portfolio company of a16z.

Trunk publishes 2 APIs on the APIs.io network: Flaky Tests API and Merge Queue API. Tagged areas include Developer Tools, CI/CD, Code Quality, Flaky Tests, and Merge Queue.

The Trunk catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Trunk’s developer surface includes documentation, engineering blog, authentication, CLI, and 20 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/trunk: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
