  • Milkman

    Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore i created a JavaFx-based workbench for crafting requests / responses. It is not limited to e.g. http (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database-requests or GRPC, GraphQl, etc...
