Milkman is an extensible request/response workbench inspired by Postman, built with JavaFX instead of Electron for fast startup and low memory usage. Nearly everything is a plugin, allowing it to handle HTTP/REST requests as well as gRPC, GraphQL, and database requests.

Use cases

• craft and test REST API requests without Postman
• find a lightweight Postman alternative that isn't Electron-based
• import Postman or Insomnia collections into a local tool
• manage API requests with environments and workspaces
• send gRPC or GraphQL requests from a desktop client
• organize API requests into collections without an account

When to choose

• you want a fast, native-feeling API client without Electron overhead
• you need a Postman/Insomnia alternative with no forced account
• you need extensibility via plugins for gRPC, GraphQL, or database requests
• you work across Windows, macOS, or Linux

When to avoid

• you need team collaboration or cloud-sync features built in
• you prefer browser-based API clients
• you need extensive scripting/test suites like Postman's Newman ecosystem
