   Apidog▲570

   Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

    Mock Studio▲3

    Hi HN, I built this after using Requestly, Mokku, Mockiato, Tweak, and Mockoon. Each one either paywalled the features I actually needed, required a separate server running on my machine, or just didn't fit the way I work. The browser is already open. DevTools is already open. I wanted the mocking to live there too, not in a separate app I have to remember to start. So roughly a month ago, I started building my own tools. It intercepts network requests at the browser level and lets you swap the response, status code, headers, body without touching your code or spinning up anything.…
