macOS Terminal Comparison: Warp vs. Ghostty vs. iTerm2 vs. Default
The built-in Terminal app works, but most developers who live in the command line eventually try something else. This guide compares the three most popular replacements on Mac, Warp, Ghostty, and iTerm2, with Apple's own Terminal.app.
A lot has changed since we first wrote this. Warp is now open source and calls itself an agentic development environment, iTerm2 has a GPU renderer and a built-in AI chat, and Ghostty has matured into a fast, native terminal with desktop notifications and scrollback search.
Quick Verdict
- Warp is the pick if you want AI agents built into the terminal, an editor-like input, and cloud features for teams.
- Ghostty is the pick if you want a fast, native, minimal terminal configured with a plain text file.
- iTerm2 is the pick if you want the deepest feature set: tmux integration, triggers, a Python API, and optional AI chat with your own model provider.
- Terminal.app is fine if you only open a terminal now and then and don't want to install anything.

Warp
Warp rethinks what a terminal looks like. Commands and their output are grouped into blocks you can select, copy, and share, and the input area behaves like a text editor rather than a single shell line. Since 2025, Warp has leaned hard into AI: it describes itself as "an agentic development environment, born out of the terminal". You can type natural-language requests, run agents locally or in the cloud and watch them work, review their code changes in a built-in editor, and organize sessions with vertical tabs that show git branches and worktrees.
Two big changes since our first version: Warp is now open source under the AGPL-3.0 license (warpdotdev/warp on GitHub), and it runs on macOS, Windows, and Linux. It supports bash, zsh, fish, and PowerShell on Mac.
The terminal itself is free. Paid plans add AI usage: Build is $20/month with $20 of agent usage included at API rates, Max is $200/month, and Business is $50 per user per month for teams of up to 25. The free plan includes limited cloud agent access and lets you bring your own AI inference.
Downsides: Warp is the heaviest of the four, and its blocks and editor-style input take some adjustment if you rely on traditional shell key bindings. Its AI and cloud features are where the paid plans come in.
Ghostty
Ghostty is a fast, GPU-accelerated terminal written in Zig that uses native macOS UI (real macOS tabs, windows, and splits) instead of a custom interface. It's free and open source under the MIT license, and the current release, 1.3.1, is a universal binary that requires macOS 13 or later. It also runs on Linux.
Ghostty is configured with a plain text file. It ships with hundreds of themes that can follow the system's light or dark mode, supports font ligatures, renders images with the Kitty graphics protocol, and has shell integration for bash, zsh, fish, elvish, and nushell. It can show desktop notifications when a program sends OSC 9 or OSC 777 escape sequences (on by default), has scrollback search, and supports AppleScript on macOS.
Downsides: there's no settings window to click through, no AI features, and no tmux control-mode integration. If you want a terminal that does a lot out of the box, iTerm2 or Warp will suit you better.
iTerm2
iTerm2 has been the power user's Mac terminal for years, and it keeps adding features. It's free and open source (GPLv2). The current stable release, 3.7.5, requires macOS 13 or later.
Its strengths are depth and control: flexible split panes, profiles that switch automatically, triggers that act on text matching a regular expression, regex search, a Python API for scripting, Notification Center alerts when jobs finish, and tmux integration that turns tmux windows into native iTerm2 tabs and windows. It also has its own inline images protocol.
Two corrections to our original post: iTerm2 has a GPU renderer (built on Metal) that you can turn off on battery to save energy, and it now includes AI Chat. Chats can be private conversations or linked to a terminal session, with permissions you control for reading the screen, running commands, or writing files. You pick the model provider, including local options like Ollama. There's also an optional Claude Code integration that shows each Claude session's status in iTerm2.
Downsides: the settings window is huge, and the defaults look dated until you customize them. It's Mac-only.
macOS Terminal
Apple's Terminal.app ships with every Mac and needs no setup. It supports tabs, profiles with custom colors and fonts, and AppleScript automation, and it's perfectly adequate for running occasional commands, Homebrew installs, or SSH sessions.
It lacks the features developers usually switch for: real split panes with separate sessions, inline images, ligatures, tmux integration, and notifications. If you only open a terminal a few times a week, that won't matter.
Which One Should You Choose?
- Choose Warp if you want AI agents in your terminal, like the block-based interface, or need the same terminal on Mac, Windows, and Linux.
- Choose Ghostty if you care most about speed, native macOS behavior, and a clean config file you can keep in your dotfiles.
- Choose iTerm2 if you use tmux, want triggers and scripting, or like to customize every detail, and you'd rather add AI on your own terms.
- Stick with Terminal.app if you rarely use the command line.
If you connect to remote servers a lot, also see our Termius alternatives guide, which covers SSH clients like Prompt 3, Royal TSX, and Tabby alongside iTerm2.
Final Verdict
All three replacements are free to use, so there's little risk in trying them. Warp has become the terminal for AI-assisted work, with paid plans only if you use its agents heavily. Ghostty is the best minimal, native option. iTerm2 remains the most capable traditional terminal, and its GPU renderer and AI Chat mean it no longer trails the newer apps on speed or smarts. Terminal.app is still fine for light use.
