Alacritty

A fast, cross-platform, OpenGL terminal emulator.

Alacritty is a blazing-fast, GPU-accelerated terminal emulator focused on simplicity and performance. Written in Rust, it uses OpenGL for rendering to achieve minimal input latency and high frame rates for terminal output. Alacritty intentionally omits features like tabs and splits, relying instead on integration with terminal multiplexers such as tmux for multi-window workflows. Its configuration is through a well-documented TOML file with live reload support, and it supports Vi mode, multi-window, and regex-based hinting for URLs and paths. By delegating multiplexing and session management to external tools, Alacritty maintains a lean codebase and uncompromising performance across macOS, Linux, Windows, and BSD platforms.
