Rio is a hardware-accelerated GPU terminal emulator written in Rust, designed to work as both a native desktop application and inside web browsers.Can Rio run inside a web browser, or is it only a desktop app?Rio targets both desktops and browsers: its GPU-based rendering pipeline (built on wgpu) lets the same renderer work as a native desktop terminal or be compiled for browser environments.

Rio runs natively on macOS and Linux desktops, as shown in the project's demos, and has even been demoed running on a Steam Deck, alongside browser-based execution.Does Rio need a dedicated graphics card?Yes, Rio's rendering is GPU-accelerated via the wgpu library with backends such as Vulkan and Metal, so it relies on your system's GPU rather than CPU-based rendering.
Yes, Rio's rendering is GPU-accelerated via the wgpu library with backends such as Vulkan and Metal, so it relies on your system's GPU rather than CPU-based rendering.Why is GPU acceleration important for a terminal emulator?Rendering on the GPU lets Rio smoothly handle visual effects like blurred backgrounds, split panes and CRT-style display, as shown in its platform demos, instead of relying on slower CPU-based terminal rendering.
