RUSTMAN

The Native, Blazing Fast API Client.

📖 About

Rustman is a lightweight, native alternative to tools like Postman or Insomnia. Built entirely in Rust, it ditches the heavy Electron wrappers to offer instant startup times and minimal memory usage.

Designed with the ELM Architecture and the Iced framework, Rustman proves that you can build beautiful, responsive, and type-safe GUI applications for the desktop.
