Developer builds a JavaFX Postman rival because Electron apps are too slow

Milkman – The Better Alternative to Postman

Milkman is a JavaFX-based workbench for crafting requests and responses, built by a developer tired of Electron apps that take ages and loads of memory to start. Heavily inspired by Postman, it isn't limited to HTTP/REST: nearly everything is a plugin, so database requests, gRPC, GraphQL, and more are possible. New plugins and features keep arriving, and contributions are welcome on GitHub.

I got sick of all those electron-based applications that need ages and loads of memory to start up.

    For a Postman-like experience, I prefer Bruno: https://github.com/usebruno/bruno (not affiliated)

    For something lightweight and with a native look on Mac, I use http://mmattozzi.github.io/cocoa-rest-client/

    Only HTTP/Rest but that's all I need.

    The UI looks a bit outdated, it gives me vibes of some old software from 2000s somehow (probably because of the Java).

    And it would be really helpful to clearly state benefits of using Milkman instead of Postman right on the home page (e.g. performance benchmarks, UX, extendability, etc.). I see that it has some users and 1.3k stars so there're definitely some cool things in Milkman, probably you could just present them better

    We are in an age where it’s easier to vibe code your own alternative than to do a quick internet search to check if an alternative already exists.

More from this day
