GhosttyvsiTerm2

The short version

Pick Ghostty if you want the best-feeling terminal on modern macOS with the least clutter and the most obvious performance upside.

Pick iTerm2 if you already rely on its power features, especially tmux -CC mode and the surrounding automation ecosystem.

What changed

This comparison would have been easier a year ago. The old answer was simple: iTerm2 if you were serious, Terminal.app if you were not.

Ghostty changed that. It gave macOS developers a faster, cleaner, more native terminal without asking them to settle for an Electron-style wrapper or a Linux-ish UI transplanted onto a Mac. Release 1.3.0 in March 2026 also closed some of the "nice, but not complete yet" gaps with features like scrollback search.

Where each wins

Ghostty wins on feel. The rendering is smoother, the UI is calmer, and the whole product feels designed for current hardware instead of carried forward across two decades of feature accumulation.

iTerm2 wins on depth. If you rely on triggers, profiles, shell integration, status bars, scripting, or tmux integration, it still offers more. It also benefits from years of community knowledge and documentation.

The trap here is assuming deeper automatically means better. For many developers, it doesn't. A lot of people simply want a terminal that is fast, clean, and unintrusive. That is why Ghostty has taken off so quickly.

Our recommendation

If you are choosing fresh on macOS in 2026, start with Ghostty.

If you are already deeply invested in iTerm2, especially around tmux and automation, there is still no urgent reason to leave. This is less about one tool being obsolete and more about Ghostty finally making the old default optional.
