Some changes include: • Use the with_hardware_acceleration function on the ContextBuilder to not require the discrete GPU • Remove the LMenu and RMenu virtual key codes (winit 0.16.0 removed these because Windows now generates LAlt and RAlt instead • Replace set_cursor_state with hide_cursor (winit 0.16.0 removed the set_cursor_state function) • Replace GlWindow::hidpi_factor with GlWindow::get_hidpi_factor and change to expecting an f64 • Use the glutin/winit dpi size and position types where possible Glutin's dpi change event has been implemented. All size events now return logical sizes. As a result of that, the logical sizes are translated in the `display::handle_rezize` method so DPI scaling works correctly. When the DPI is changed, the glyph cache is updated to make use of the correct font size again. Moving a window to a different screen which is a different DPI caused a racing condition where the logical size of the event was sent to the `handle_resize` method in `src/display.rs`, however if there was a DPI change event before `handle_resize` is able to process this message, it would incorrectly use the new DPI to scale the resize event. To solve this issue instead of sending the logical size to the `handle_resize` method and then converting it to a physical size in there, the `LogicalSize` of the resize event is transformed into a `PhysicalSize` as soon as it's received. This fixes potential racing conditions since all events are processed in order. The padding has been changed so it's also scaled by DPR. The `scale_with_dpi` config option has been removed. If it's not present a warning will be emitted. The `winit` dependency on Windows has been removed. All interactions with winit in Alacritty are handled through glutin. |

Alacritty
Alacritty is the fastest terminal emulator in existence. Using the GPU for rendering enables optimizations that simply aren't possible in other emulators. Alacritty currently supports macOS, Linux, and Windows.
About
Alacritty is focused on simplicity and performance. The performance goal means it should be faster than any other terminal emulator available. The simplicity goal means that it doesn't have features such as tabs or splits (which can be better provided by a window manager or terminal multiplexer) nor niceties like a GUI config editor.
The software is considered to be at an alpha level of readiness--there are 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.

Installation
Some operating systems already provide binaries for Alacritty, for everyone else the instructions to build Alacritty from source can be found here.
Arch Linux
pacman -S alacritty
Debian/Ubuntu
Using cargo deb
, you can create and install a deb file.
git clone https://github.com/jwilm/alacritty.git
cd alacritty
cargo install cargo-deb
cargo deb --install
openSUSE Tumbleweed
zypper in alacritty
Void Linux
xbps-install alacritty
Gentoo Linux
emerge x11-terms/alacritty
FreeBSD
pkg install alacritty
Other
Prebuilt binaries for Linux, macOS, and Windows can be downloaded from the GitHub releases page.
Configuration
Although it's possible the default configuration would work on your system,
you'll probably end up wanting to customize it anyhow. There is a default
alacritty.yml
, alacritty_macos.yml
, and alacritty_windows.yml
at the Git repository root.
Alacritty looks for the configuration file as the following paths:
$XDG_CONFIG_HOME/alacritty/alacritty.yml
$XDG_CONFIG_HOME/alacritty.yml
$HOME/.config/alacritty/alacritty.yml
$HOME/.alacritty.yml
If none of these paths are found then
$XDG_CONFIG_HOME/alacritty/alacritty.yml
is created once Alacritty is first
run. On most systems this often defaults to
$HOME/.config/alacritty/alacritty.yml
.
Many configuration options will take effect immediately upon saving changes to
the config file. The only exception is the font
and dimensions
sections
which requires Alacritty to be restarted. For further explanation of the config
file, please consult the comments in the default config file.
Windows
On Windows the config file is located at:
%UserProfile%\alacritty.yml
Issues (known, unknown, feature requests, etc.)
If you run into a problem with Alacritty, please file an issue. If you've got a
feature request, feel free to ask about it. Keep in mind that Alacritty is very
much not looking to be a feature-rich terminal emulator with all sorts of bells
and widgets. It's primarily a cross-platform, blazing fast tmux
renderer that
Just Works.
FAQ
Is it really the fastest terminal emulator?
In the terminals I've benchmarked against, Alacritty is either faster, WAY faster, or at least neutral. There are no benchmarks in which I've found Alacritty to be slower.
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.
My arrow keys don't work.
It sounds like you deleted some key bindings from your config file. Please reference the default config file to restore them.
IRC
Alacritty discussion can be found in #alacritty
on freenode.
Wayland
Wayland support is available, but not everything works as expected. Many people
have found a better experience using XWayland which can be achieved launching
Alacritty with the WAYLAND_DISPLAY
environment variable cleared:
env WAYLAND_DISPLAY= alacritty
If you're interested in seeing our Wayland support improve, please head over to the Wayland meta issue on the winit project to see how you may contribute.
