   Mocktail – Free, open-source mock API server with a built-in dashboard▲25

   Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required.

    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.
