About 120.dev

At 120.dev, we're revolutionizing applications by creating truly native experiences that run seamlessly across macOS, Windows, and Linux.

Our vision is simple: native apps should offer high efficiency, sleek design, and cross-platform flexibility. Our goal is to push the limits of software performance, delivering fluid, responsive, and future-proof applications.

To achieve this goal, we build our components from the ground up, emphasizing on extensive theming capabilities and adaptable designs. We then integrate these clean layouts, customizable components into high-performance native technology to create applications that not only feel smooth (up to 120FPS) but also provide a consistent experience across platforms.
