The short answer

Pick iTerm2 if you are on a Mac and want a classic, deeply configurable terminal that is free and needs no account. Pick Warp if you want AI agents, command blocks and an editor-style input line, or need the same terminal on Windows and Linux. The biggest difference is philosophy: iTerm2 refines the traditional terminal, while Warp rebuilds it around AI.

iTerm2 or Warp: our take

iTerm2 has been developed for well over a decade and behaves like a traditional terminal with a very long feature list on top: split panes, a drop-down hotkey window, profiles that switch by host or directory, triggers that react to output, shell integration and a Python scripting API. Its tmux integration, which shows tmux windows as native tabs and splits, is still unusual. The cost of all that breadth is a settings window many people find hard to navigate, and it can feel slower than GPU-first terminals on very heavy output.

Warp changes how the command line works. Each command and its output form a block you can copy, search or share, and the input area acts like a text editor with mouse selection and multi-line editing. Its main focus is now AI: built-in agents can run commands and edit code across files. Because it departs from classic terminal behaviour, some shell setups need adjusting, and some developers dislike how much the product centres on AI and accounts.

Pricing and platforms separate them clearly. iTerm2 is free, GPL-2.0 licensed, funded by donations and runs only on macOS. Warp runs on macOS, Windows and Linux and has been open-sourced under AGPL-3.0; the terminal itself is free, and the Build plan costs $20/month with $20 of agent usage for people who lean on its AI features.

For a Mac user who lives in tmux, SSH sessions and long-lived dotfiles, iTerm2 is the safer choice and costs nothing. For a developer who wants AI help inside the terminal, or a single tool across three operating systems, Warp is the better fit, as long as its non-traditional design and paid AI credits are acceptable.

Choose iTerm2 if…

Mac users who want a mature, highly configurable terminal with tmux integration
Huge, mature feature set including triggers and shell integration
Native tmux integration with tabs and splits

Choose Warp if…

Developers who want AI agents and an editor-like command line in one terminal
You need Windows and Linux, which iTerm2 doesn't list
Command blocks and editor-style input
Built-in AI agents that can run commands and edit code

What is iTerm2?

iTerm2 is a free, open-source terminal emulator for macOS and the most common upgrade from Apple's built-in Terminal. It has been developed for well over a decade, mostly by George Nachman, and has accumulated an enormous feature list: split panes, a hotkey window that drops down from anywhere, profiles that switch automatically by host or directory, search with regular expressions, triggers that react to output, instant replay of the screen, and shell integration that marks commands and lets you jump between them. Its tmux integration shows tmux windows and panes as native tabs and splits. There is a Python API for scripting, optional AI features that need your own API key, and extensive appearance settings. It is free and GPL licensed, funded by donations. The breadth of settings can be overwhelming, it is macOS only, and newer GPU-first terminals feel snappier with very large outputs.

What is Warp?

Warp is a terminal written in Rust that rethinks the interface: each command and its output form a block you can copy, share or search, and the input area behaves like a text editor with mouse selection and multi-line editing. Its main focus is now AI: Warp's agents can run commands, edit code and work across files, and the company positions the product as an agentic development environment, with a separate platform for running fleets of coding agents. Other features include completions for hundreds of tools, saved workflows, team sharing of commands and a built-in file editor. Warp runs on macOS, Windows and Linux and has been open-sourced under the AGPL licence. The terminal is free, while paid plans add monthly AI usage credits and team features. Some developers dislike the heavy AI emphasis and the account features, and it differs enough from a classic terminal that some shell setups need adjusting.
