## About
|
|
|
|
Alacritty is a modern terminal emulator that comes with sensible defaults, but
|
|
allows for extensive [configuration](#configuration). By integrating with other
|
|
applications, rather than reimplementing their functionality, it manages to
|
|
provide a flexible set of [features](./docs/features.md) with high performance.
|
|
The supported platforms currently consist of BSD, Linux, macOS and Windows.
|
|
|
|
The software is considered to be at a **beta** level of readiness; there are
|
|
a few missing features and bugs to be fixed, but it is already used by many as
|
|
a daily driver.
|
|
|
|
Precompiled binaries are available from the [GitHub releases page](https://github.com/alacritty/alacritty/releases).
|
|
|
|
## Features

|
|
macOS and Windows.
|
|
|
|
Prebuilt binaries for macOS and Windows can also be downloaded from the
|
|
[GitHub releases page](https://github.com/alacritty/alacritty/releases).
|
|
|
|
For everyone else, the detailed instructions to install Alacritty can be found
|
|
[here](INSTALL.md).
|
|
|
|
### Requirements
|
|
|
|
- OpenGL 3.3 or higher
|
|
- [Windows] ConPTY support (Windows 10 version 1809 or higher)
|
|
|
|
## Configuration
|
|
|
|
You can find the default configuration file with documentation for all available
|
|
fields on the [GitHub releases page](https://github.com/alacritty/alacritty/releases) for each release.
|
|
|
|
Alacritty doesn't create the config file for you, but it looks for one in the
|
|
following locations:
|
|
|
|
1. `$XDG_CONFIG_HOME/alacritty/alacritty.yml`
|
|
2. `$XDG_CONFIG_HOME/alacritty.yml`
|
|
3. `$HOME/.config/alacritty/alacritty.yml`
|
|
4. `$HOME/.alacritty.yml`
|
|
|
|
### Windows
|
|
|
|
On Windows, the config file should be located at:
|
|
|
|
`%APPDATA%\alacritty\alacritty.yml`
|
|
|

## FAQ
|
|
|
|
**_Is it really the fastest terminal emulator?_**
|
|
|
|
Benchmarking terminal emulators is complicated. Alacritty uses
|
|
[vtebench](https://github.com/alacritty/vtebench) to quantify terminal emulator
|
|
throughput and manages to consistently score better than the competition using
|
|
it. If you have found an example where this is not the case, please report a
|
|
bug.
|
|
|
|
Other aspects like latency or framerate and frame consistency are more difficult
|
|
to quantify. Some terminal emulators also intentionally slow down to save
|
|
resources, which might be preferred by some users.
|
|
|
|
If you have doubts about Alacritty's performance or usability, the best way to
|
|
quantify terminal emulators is always to test them with **your** specific
|
|
usecases.
|
|
|
|
**_Why isn't feature X implemented?_**
|
|
|
|
Alacritty has many great features, but not every feature from every other
|
|
terminal. This could be for a number of reasons, but sometimes it's just not a
|
|
good fit for Alacritty. This means you won't find things like tabs or splits
|
|
(which are best left to a window manager or [terminal multiplexer][tmux]) nor
|
|
niceties like a GUI config editor.
