Alacritty is a modern terminal emulator that comes with sensible defaults, butallows for extensiveconfiguration. By integrating with otherapplications, rather than reimplementing their functionality, it manages toprovide a flexible set offeatures with high performance.The supported platforms currently consist of BSD, Linux, macOS and Windows.

The software is considered to be at abeta level of readiness; there area few missing features and bugs to be fixed, but it is already used by many asa daily driver.

Precompiled binaries are available from theGitHub releases page.

You can find an overview over the features available in Alacrittyhere.

• Announcing Alacritty, a GPU-Accelerated Terminal Emulator January 6, 2017
• A talk about Alacritty at the Rust Meetup January 2017 January 19, 2017
• Alacritty Lands Scrollback, Publishes Benchmarks September 17, 2018

Alacritty can be installed by using various package managers on Linux, BSD,macOS and Windows.

Prebuilt binaries for macOS and Windows can also be downloaded from theGitHub releases page.

For everyone else, the detailed instructions to install Alacritty can be foundhere.

• At least OpenGL ES 2.0
• [Windows] ConPTY support (Windows 10 version 1809 or higher)

You can find the documentation for Alacritty's configuration inman 5 alacritty, or by looking atthe website if you do not have the manpagesinstalled.

Alacritty doesn't create the config file for you, but it looks for one in thefollowing locations:

1. $XDG_CONFIG_HOME/alacritty/alacritty.toml
2. $XDG_CONFIG_HOME/alacritty.toml
3. $HOME/.config/alacritty/alacritty.toml
4. $HOME/.alacritty.toml

On Windows, the config file will be looked for in:

• %APPDATA%\alacritty\alacritty.toml

A guideline about contributing to Alacritty can be found in theCONTRIBUTING.md file.

Is it really the fastest terminal emulator?

Benchmarking terminal emulators is complicated. Alacritty usesvtebench to quantify terminal emulatorthroughput and manages to consistently score better than the competition usingit. If you have found an example where this is not the case, please report abug.

Other aspects like latency or framerate and frame consistency are more difficultto quantify. Some terminal emulators also intentionally slow down to saveresources, which might be preferred by some users.

If you have doubts about Alacritty's performance or usability, the best way toquantify terminal emulators is always to test them withyour specificusecases.

Why isn't feature X implemented?

Alacritty has many great features, but not every feature from every otherterminal. This could be for a number of reasons, but sometimes it's just not agood fit for Alacritty. This means you won't find things like tabs or splits(which are best left to a window manager orterminal multiplexer) norniceties like a GUI config editor.
