API Design Tools

Mulesoft

The only brand with a recorded score (66), appearing in early 2026 samples. Even that signal is thin—one or two prompts—but it stands alone in an otherwise silent dataset.

Postman

Listed among candidates yet carries a null score, implying mentions exist but citation strength never crossed scoring thresholds. Postman is a known API testing heavyweight, so the gap hints at data-collection timing or query scope.

Stoplight

Zero score and no trend presence. Stoplight appears in the candidate pool but generated no measurable citation activity in the sample window, suggesting low AI-recommendation frequency for design-specific workflows.

OpenAPI

Null score despite being the de facto API specification standard. The absence may reflect that OpenAPI is cited as a format rather than a 'tool,' falling outside product-recommendation queries.

Kong Insomnia

Null score and no monthly data points. Insomnia is a recognized REST client, but the data window captured no citations, indicating either niche usage or low visibility in the prompt set analyzed.
