The best terminal for Mac
There is no single best terminal, only the best one for how you work. Below is an honest comparison of the strong macOS options. We build cmux, so we will be upfront: cmux is built for multitasking, organization, and programmability, and we will say where the others are the better call.
At a glance
| Terminal | Built for | Renderer | Platform |
|---|---|---|---|
| cmux | Multitasking, organization, programmability (AI agents) | GPU (libghostty) | macOS |
| Ghostty | A fast, clean single terminal | GPU | macOS, Linux |
| iTerm2 | Maximum features and configurability | GPU / CPU | macOS |
| Warp | Built-in AI and a blocks UI | GPU | macOS, Linux, Windows |
| Terminal.app | Zero-setup default | CPU | macOS |
| Alacritty | Minimal, fast, config-file only | GPU | cross-platform |
| kitty | Fast, scriptable, feature-rich | GPU | macOS, Linux |
| WezTerm | GPU terminal with a built-in multiplexer | GPU | cross-platform |
| tmux | Multiplexing inside any terminal | n/a | Unix |
cmux
cmux is a native macOS terminal built on Ghostty's terminal engine, libghostty. That means the terminal grid inherits Ghostty's strengths: fast GPU rendering, excellent font and color rendering, modern terminal compatibility, and your existing Ghostty themes, fonts, colors, and cursor settings. cmux adds the layer Ghostty intentionally does not try to be: vertical workspaces, split panes, notification rings, git/port/agent context in the sidebar, a scriptable CLI and Unix socket, a programmable browser, and an iOS companion. Pick cmux when you want Ghostty-quality terminal rendering plus organization and automation for many tasks or AI coding agents.
Ghostty
Ghostty is the fast, native terminal whose engine, libghostty, powers cmux. Compared with older CPU-rendered terminals and heavier Electron-style terminals, Ghostty's strengths are low-latency GPU rendering, crisp font and color handling, strong terminal compatibility, simple file-based configuration, and no cloud account requirement. If you want one clean terminal window with those rendering advantages and no workspace or automation layer, Ghostty is excellent on its own. If you want those same Ghostty rendering advantages plus workspaces, notifications, scripting, and agent orchestration, use cmux.
iTerm2
The mature, endlessly configurable macOS terminal. Deep profiles, triggers, and tmux integration. The safe default if you want maximum features and are not orchestrating many tasks at once.
Warp
A Rust terminal with a built-in AI assistant and a blocks command UI, behind an account, and available beyond macOS. A good fit if you want AI baked into the terminal itself or need Linux and Windows too.
Terminal.app
The built-in macOS terminal. Always there, zero setup. Fine for light use; most power users eventually want more.
Alacritty, kitty, and WezTerm
Fast GPU terminals for people who like configuring everything in a file. Alacritty is deliberately minimal, kitty is feature-rich and scriptable, and WezTerm bundles its own multiplexer. All are cross-platform and a good fit if a single, highly tuned terminal is what you want.
tmux
Not a terminal but a multiplexer you run inside one. Unbeatable for persistent sessions over SSH on remote servers. cmux can attach to remote tmux sessions when you need that.
cmux is free and open source for macOS.
