API Fortress

API Fortress was an API testing and monitoring platform that let engineering teams author, run, and continuously monitor functional and integration tests against REST and SOAP APIs, in the cloud or via an on-premise Docker-based agent. It was acquired by Sauce Labs in January 2020 and its capabilities were folded into the Sauce Labs API Testing product. The standalone apifortress.com developer surface has since been retired; as of this enrichment pass the domain no longer resolves (parked Route53 nameservers, no A records), the apifortress GitHub organization returns 404, and there is no live first-party API, docs, SDK, or well-known surface remaining to enrich.

API Fortress is profiled on the APIs.io network. Tagged areas include Company, API Testing, API Monitoring, Continuous Testing, and Quality Assurance.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/api-fortress: open an issue to ask a question, or submit a pull request to add artifacts.
