Alacritty is a modern terminal emulator that comes with sensible defaults, but allows for extensive configuration. By integrating with other applications, rather than reimplementing their functionality, it manages to provide a flexible set of features 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.
Besides Alacritty's functionality as a terminal emulator, there are a couple of features targeted at making life easier for people that spend a lot of time with their terminal.
These are some of Alacritty's noteworthy features:
Vi Mode—Move around and create selections using vi bindings
Search—Search for any text within the scrollback buffer
Regex Hints—Mark any text for mouse or keyboard interaction
