Alacritty vs iTerm2

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.

iTerm2 is feature-rich terminal emulator for macOS with split panes, search, autocomplete, and extensive customization. It provides comprehensive features for terminals workflows. The tool is actively maintained with regular updates and strong community/vendor support.
