Alacritty is a free and open-source GPU-accelerated terminal emulator focused on performance and simplicity. Consequently, it does not support tabs or splits and is configured by editing a text file. It is written in Rust and uses OpenGL (for performance).[4][5][6] A similar terminal emulator that uses OpenGL is kitty.
Joe Wilm announced Alacritty in his blog on 6 January 2017. He describes it as "the result of frustration with existing terminal emulators. Using vim inside tmux in many terminals was a particularly bad experience. None of them were ever quite fast enough". He found urxvt and st difficult to configure and criticized their "inability to run on non-X11 platforms".[1]
With the release of version 0.2.0 in September 2018 Alacritty gained support for scrollback.[7]
In version 0.3.0, released in April 2019, Alacritty entered beta stage and support for Windows, text reflow, and clicking on URLs was added.[8]
In version 0.5.0, released in July 2020, a mode with vi keybindings for searching and copying text was added.[9]
In version 0.6.0, released in November 2020, a new Ctrl+C binding to cancel search and leave vi mode was added.[10]
Alacritty supports true color in addition to the standard 16 ANSI colors.[11]
Alacritty explicitly does not support tabs or splits because similar functionality can be achieved with a terminal multiplexer or window manager.[12][13]
Alacritty is configured by editing a template file in YAML format, for example:[5]
colors:
primary:
background: '#000000'
