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.
Specs
Pros
Pro Blazing fast rendering with GPU-accelerated
Written in Rust with a philosophy focusing on speed and simplicity, Alacritty is one of the fastest terminal emulators out there.
Pro Comprehensive font options
Alacritty can be configured to adjust line spacing (height), letter spacing (width), and individual character horizontal/vertical positions.
Pro Simple configuration
The configuration file is very well made and easy to use. You can fine tune your preferences to perfection in a matter of minutes.
Cons
Con Unreliable Font Rendering
Like a box of chocolate you never know what you're going to get.
Con Sacrifices basic features for raw performance
The Suzuki GSXR of terminals. Or your ditzy, blonde high school cheerleader; fast and pretty but not a lot going on under the hood.
Eschews a negative developmental philosophy towards including said functionality, with the official reason cited in project documentation as "Not within the realm of a terminal emulator" and ostensibly, "best left up to other tools such as terminal multiplexers" [such as screen or tmux]. Which is unfortunate when you factor in speed against terminal with the functionality built in vs their reliance on 3rd party tools:
tmux on alacritty: 'find /usr' time: 3.234s, cpu: 72%
tmux on konsole: find /usr' time: 1.777s, cpu: 96%
