    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.

It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined. Been a long time lurker here and…
