Alacritty vs Ghostty

Alacritty is a free, cross-platform terminal emulator for Linux, macOS, Windows, and BSD. It uses OpenGL and is designed for high performance and extensive configuration, for people who spend substantial time in a terminal. Vi mode supports viewport and scrollback navigation, text selection, and copying with keyboard bindings; users can also search forward or backward through scrollback. Configurable regex hints can recognize visible text or links and pass them to an external application or trigger a built-in action. One instance can run multiple terminal windows, including through the alacritty msg create-window command. Alacritty is designed to integrate with other applications rather than recreate their functions, and URL-opening applications can be configured. Settings use a TOML file that the software does not create automatically. The project describes Alacritty as beta, with missing features and bugs still to address. It has no tabs, split panes, or graphical configuration editor, and requires OpenGL ES 2.0. Windows use requires ConPTY support on Windows 10 version 1809 or higher.

Ghostty is a free, open-source terminal emulator for macOS and Linux. It renders with Metal on macOS and OpenGL on Linux for GPU acceleration, while native interface components provide multiple windows, tabs, and split panes. Its shared libghostty core handles terminal emulation, fonts, and rendering through a cross-platform C ABI. Ghostty includes hundreds of themes and can follow system light and dark modes automatically. It supports the Kitty graphics protocol for terminal images and provides automatic shell integration for bash, elvish, fish, nushell, and zsh. SSH integration can forward environment variables and install Ghostty terminfo entries on remote hosts. macOS Secure Keyboard Entry helps protect passwords from other processes, and official macOS binaries are signed and notarized. Ghostty is licensed under MIT and fiscally sponsored by Hack Club, a 501(c)(3) nonprofit. Community help is available through GitHub Discussions and Discord; there is no dedicated support team. The Ghostty plan is free, described as free and open source with no commercial backing.
