Alacritty vs Guake

Alacritty is an open-source, GPU-accelerated terminal emulator focused on simplicity and performance. It uses OpenGL for rendering, making it one of the fastest terminal emulators available. Alacritty is configured through a YAML file and intentionally omits features like tabs and splits, relying on terminal multiplexers like tmux for those capabilities.

Guake is a terminals tool that gnome drop-down terminal inspired by the quake console with quick toggle visibility on a hotkey. It is open source software.
