Alacritty is the fastest terminal emulator in existence. Using the GPU for
|
|
rendering enables optimizations that simply aren't possible without it.
|
|
Alacritty currently supports macOS, Linux, BSD, and Windows.

## About
|
|
|
|
Alacritty is a terminal emulator with a strong focus on simplicity and
|
|
performance. With such a strong focus on performance, included features are
|
|
carefully considered and you can always expect Alacritty to be blazingly fast.
|
|
By making sane choices for defaults, Alacritty requires no additional setup.
|
|
However, it does allow [configuration](#configuration) of many aspects of the
|
|
terminal.
|
|
|
|
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).

Once the cask is installed, it is recommended to setup the [manual page](INSTALL.md#manual-page),
|
|
[shell completions](INSTALL.md#shell-completions), and [terminfo definitions](INSTALL.md#terminfo).
|
|
|
|
### Windows
|
|
|
|
#### Via [Chocolatey](https://chocolatey.org)

|
|
|
```batch
|
|
choco install alacritty
|
|
```
|
|
|
|
#### Via [Scoop](https://scoop.sh)
|
|
|
|
```batch
|
|
scoop bucket add extras
|
|
scoop install alacritty
|
|
```
|
|
|
|
### Other
|
|
|
|
Prebuilt binaries for Linux, macOS, and Windows can be downloaded from the
|
|
[GitHub releases page](https://github.com/alacritty/alacritty/releases). If your
|
|
desktop environment has trouble rendering the default SVG icons, you can find
|
|
a prerendered SVG as well as simplified versions of the SVG in the
|
|
`extra/logo/compat` directory.
|
|
|
|
On Windows, Alacritty also requires Microsoft's VC++ redistributable.
|
|
|
|
For Windows versions older than Windows 10 (October 2018 Update), Alacritty
|
|
requires winpty to emulate UNIX's PTY API. The agent is a single binary
|
|
(`winpty-agent.exe`) which **must** be in the same directory as the Alacritty
|
|
executable and is available through the
|
|
[GitHub releases page](https://github.com/alacritty/alacritty/releases).
|
|
|
|
## 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`
|
|

|
|
that goal.

## FAQ
|
|
|
|
**_Is it really the fastest terminal emulator?_**
|
|
|
|
In the terminals we've [benchmarked](http://github.com/alacritty/vtebench),
|
|
Alacritty is either faster or **way** faster than the others. If you've found a
|
|
case where this isn't true, please report a bug.
|
|
|
|
**_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.
|
|
|
|
**_macOS + tmux + vim is slow! I thought this was supposed to be fast!_**
|
|
|
|
This appears to be an issue outside of terminal emulators; either macOS has an
|
|
IPC performance issue, or either tmux or vim (or both) have a bug. This same
|
|
issue can be seen in `iTerm2` and `Terminal.app`. I've found that if tmux is
|
|
running on another machine which is connected to Alacritty via SSH, this issue
|
|
disappears. Actual throughput and rendering performance are still better in
|
|
Alacritty.
|
|
|
|
## IRC
|
|
|
|
Alacritty discussion can be found in `#alacritty` on freenode.
|
|
|
|
## Wayland
|
|
|
|
Wayland is used by default on systems that support it. Using XWayland may
|
|
circumvent Wayland specific issues and can be enabled through:
|
|
|
|
```sh
|
|
env WINIT_UNIX_BACKEND=x11 alacritty
|
|
```
