Microcks

Microcks is an open source, cloud-native tool for API mocking and testing. It provides a platform for importing API contracts (OpenAPI, AsyncAPI, Postman Collections), generating mock responses, and running test suites. It shortens the feedback loop for API development teams.

Microcks publishes 6 APIs on the APIs.io network, including config API, job API, metrics API, and 3 more. Tagged areas include API Testing, Cloud-Native, DevOps, Mocking, and Open-Source.

Microcks’ developer surface includes authentication, developer portal, documentation, engineering blog, and 8 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/microcks: open an issue to ask a question, or submit a pull request to add artifacts.
