About:
Milkman is an extensible, cross-platform desktop application designed for API development and testing. It functions as a comprehensive workbench for crafting, sending, and analyzing HTTP and other types of requests, with a plugin-based architecture for extended functionality. Its main value is providing a flexible, open-source alternative to commercial API clients for developers and testers.
Key Features:
  • Extensible plugin system for custom protocols and features
  • Support for HTTP, REST, GraphQL, and other request types via plugins
  • Organize requests into collections and environments
  • Scripting capabilities for request/response manipulation
  • Cross-platform desktop application (Java-based)
Use Cases:
  • API development and debugging for backend services
  • Testing RESTful or GraphQL endpoints during development
  • Organizing and documenting API requests for team projects
Alternatives:
  • Postman – More widely adopted with cloud features; Milkman is open-source and locally focused.
  • Insomnia – Similar core functionality; Milkman emphasizes extensibility via plugins.
