Good fit if
- You work on Windows with WSL (Windows Terminal is the pick)
- You want the same terminal on three operating systems (WezTerm is the pick)
- You want the lowest latency and use tmux anyway (Alacritty is the pick)
- You are on a Mac and want menus, profiles and search (iTerm2 is the pick)
Not ideal if
- You cannot host, patch and back up a server yourself and want a vendor to run it
A terminal emulator is the window your shell lives in, and the differences are speed, features and platform. Alacritty and Ghostty chase minimal latency by drawing text on the GPU, and both keep configuration to a text file. Kitty and WezTerm add built-in extras such as image display, tabs and splits, and scripting, so you can skip tmux for many tasks; WezTerm configures through Lua and runs on all three desktop systems. iTerm2 is the long-standing macOS favourite with profiles, search and shell integration, while Windows Terminal is the modern default on Windows, with tabs for PowerShell, Command Prompt and WSL. The trade-off is simplicity versus bundled features. A minimal terminal feels instant but leaves multiplexing to tmux, while a feature-rich one means fewer extra tools to learn and more settings to understand. Check platform support before you fall in love with one: Ghostty and Kitty cover macOS and Linux but not Windows, Alacritty and WezTerm cover all three, and iTerm2 and Windows Terminal each cover only their own operating system. If you share dotfiles across machines, favour a terminal whose config is a single file that works everywhere, and test how it handles your fonts and ligatures.
