Rio Overview
Rio is a free, open-source, GPU-accelerated terminal emulator for Windows, macOS, and Linux (and the web), built in Rust with a focus on speed and modern rendering. It uses the GPU to draw the terminal quickly and supports features expected of a modern terminal: tabs and splits, ligatures, true color, and configurable themes and fonts, with cross-platform consistency. Its emphasis on performance and a clean, modern codebase appeals to developers who want a fast, lightweight terminal. Being open source and actively developed, it is part of a wave of Rust-based terminals. The full offline/portable build runs without an internet connection. It also supports a Vi-style navigation mode and runs natively across platforms with a consistent configuration. This page links to the official Rio download.
