At Yasumu, we are on a mission to build a free, open-source API testing platform for developers that is intuitive and powerful. Our tools are designed with simplicity in mind, making API testing easier for everyone. Whether you're a seasoned developer or just starting out, our platform offers the features you need without unnecessary complexity.
Yasumu is built using modern, efficient technologies like Tauri, React, and TypeScript, providing a lightweight yet powerful interface for testing APIs. Unlike traditional API testing platforms, Yasumu is focused on speed, privacy, and minimal resource usage, making it an excellent alternative to commercial tools such as Postman, Insomnia*, or Bruno*.
*Has both Open Source and Paid version.
