Terminal apps replace macOS's built-in Terminal with faster rendering, split panes, better font and color handling and deeper configuration. GPU-accelerated terminals stay responsive under heavy output, while others focus on extras such as SSH session management or AI command help.
iTerm2 is the long-standing native favorite with extensive settings. Ghostty is a fast GPU-accelerated terminal with a native macOS interface, and Alacritty, kitty and WezTerm are GPU-accelerated and configured through text files. Warp adds command blocks and AI features, while Tabby and Hyper are Electron-based and use more memory. Most options here are free.
