Ranked in these QuestionsQuestion Ranking
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 Looks good
Alacritty looks very slick on Linux, especially with GNOME or i3.
Pro Comprehensive font options
Alacritty can be configured to adjust line spacing (height), letter spacing (width), and individual character horizontal/vertical positions.
Pro Has support for image previews in w3m and ranger
Pro It looks just beautiful
Pro It's open source
This helps the community to move software forward and to make it even better.
Pro Under active development
Hyper development has basically stalled out.
Pro It comes with plugins
Pro Is cross-platform
Even the question was "...for Windows", it's nice if you can use your tools over different platforms.
A lot of things can be easily configured, e.g. color theme, size, window frame behavior, tab location, cursor style, hotkeys, etc.
Pro Integrated GitBash, Cmd, PowerShell, and WSL
Pro Integrates with git-bash with a simple toggle in the interface
Pro Excellent interface
At start opens last session terminals. Also has terminal tabs.
Con No text re-flow when window is resized
Latest versions not only perform re-flow, but it is done fast af.
Con Cannot into ligatures
Alacritty not support ligatures in Fira Code, Iosevka etc.
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%
See issue here.
Con Some functions still fail
It's huge. The amount of resources it consumes is not justifiable.
Con Slow with input lag
Sadly, Electron strikes again. The input lag is noticeable and annoying. Startup also takes like 2 seconds or more (On an i7 from 2016 with SSD).
Con Cannot remove the default profiles
For example, you installed Arch Linux for Windows Subsystem for Linux some time ago, but now you have deleted it and currently use Ubuntu on WSL. After that, if you decide to try this terminal emulator, you'll find Arch there without an option to remove the profiles already included in Terminus.
Con Easy to be confused with different brands of the same or similar name
Like Terminus (Russian production company), Terminus (font) or Termius (SSH client).
Con No multi window support
Can't split tabs into multiple windows.
