## What it is
Rio is a hardware-accelerated terminal emulator written in Rust using wgpu (Metal/Vulkan), available for macOS, Windows, Linux, FreeBSD, and WebAssembly. It supports modern terminal features like split panels, vi mode, image protocols (Sixel, iTerm2, Kitty), and runs in desktops and browsers.

## Use cases
- gpu-accelerated terminal emulator for macos
- fast terminal with split panels
- terminal emulator that runs in the browser
- terminal with kitty graphics and sixel image support
- cross-platform terminal for windows linux and freebsd
- rust terminal emulator with vi mode
- terminal with adaptive light and dark themes

## When to choose
- you want a fast, GPU-rendered terminal with low input latency
- you need one terminal across macOS, Windows, Linux, FreeBSD, and the web
- you want modern features like split panels, vi mode, image protocols, and retroarch shaders
- you prefer a TOML-configurable terminal with live config reload and theming

## When to avoid
- you need a terminal that runs without GPU acceleration on very old hardware
- you rely on an ecosystem of plugins or extensions specific to another emulator
- you need a minimal, dependency-free terminal for embedded or headless servers

## Facets
- artifact type: application
