iTerm2 vs Warp
These two terminals answer different questions. iTerm2 is a free, GPL v2 replacement for the stock Mac Terminal, written by George Nachman, and its home page asks for nothing beyond a download. Warp is built for AI-assisted development and sells a Free plan plus Build, Max, Business and Enterprise tiers, with agent usage metered above each allowance. If you only want a good shell on a Mac, iTerm2 has no meter to watch. If you want agents running inside the terminal, Warp is the one that offers them.
Sebastiaan SmitsFounderVendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
Choose iTerm2 ifyou work on a Mac running macOS 10.14 or newer and want a free terminal with its source on GitHub. You are happy to read the separate features page and do not need AI agents built in.
Choose Warp ifyou want AI agents inside the terminal and accept that usage beyond the plan allowance is billed pay-as-you-go. You also want a vendor with a published team tier and an enterprise route.

Where they differ
iTerm2 2 · Warp 3 · open 1- 01
Zero against a ladder of tiers
iTerm2 is described as free software, and the home page links straight to a download of the latest stable release. No plan names, seat counts or usage allowances appear there. Warp lists Free at $0 a month, Build at $20, Max at $200, Business at $50 per user and Enterprise on custom terms. Anyone who only wants a shell pays nothing with iTerm2 and has a simpler decision to make.

What happens when the AI allowance runs out
Warp's Build plan includes $20 of agent usage per month at API rates, Max includes $200, and the Free plan's extra agent usage is charged at pay-as-you-go rates. That meter is the product's business model, and it is a real running cost. The iTerm2 home page names no agent features, so there is nothing to meter, but there is also nothing of that kind to use. For agent work Warp has the facts on its side.

Operating systems you can run it on
iTerm2 requires macOS 10.14 or newer and, by the pages we read, supports nothing else. That is a hard limit for anyone who also works on Linux or Windows machines. The Warp pages we read do not show which operating systems it runs on, so we cannot score this round for Warp. Check Warp's download page before you commit a mixed team to it, since the pack here does not settle it.
Depends on the buyer
- 04
Open code and the licence on the box
iTerm2 is licensed under GPL v2, with the source hosted on GitHub, and that licence is stated on the home page. Warp is described as an open-source terminal built for AI-assisted software development, and its footer links to a GitHub repository labelled Open Source. The Warp pages we read do not name a licence, so the iTerm2 position is the one you can state precisely today.

Company details a buyer can find
The iTerm2 home page credits George Nachman and gives a contact email, but names no company, imprint or country. Warp's terms of service name Denver Technologies, Inc. d/b/a Warp.dev, governed by New York State law with disputes heard in New York. No country of establishment is stated for either tool. Warp at least gives a legal entity and a jurisdiction to put in a contract, which iTerm2's page does not.

Growing from one laptop to a team
Warp has a route for groups: Business at $50 per user per month with up to 25 seats and $20 of agent usage per seat, then Enterprise with unlimited seats and advanced spend controls. The company also sells Warp Factories, which run fleets of coding agents and connect to Slack, Linear, Jira, GitHub and GitLab. iTerm2's home page lists no team tier or integrations, which suits a solo user but leaves a gap for a company.

When neither fits
If you need a terminal on Linux or Windows, or want one with no vendor account at all, look at Ghostty or WezTerm. Both are in our terminal emulators category and avoid iTerm2's macOS-only limit and Warp's usage meter.
iTerm2 or Warp: questions
3 answersDoes a Mac user need to pay anything to run iTerm2 all day?
No. The home page describes iTerm2 as free software and links to a stable download. It requires macOS 10.14 or newer, and the source is on GitHub under GPL v2.
Where does Warp's cost climb past the $20 mark?
Build is $20 a month with $20 of agent usage at API rates, and extra usage is billed pay-as-you-go.
Max is $200 a month with $200 of usage, and Business is $50 per user per month. Annual billing lowers Build to $18, Max to $180 and Business to $45.
Can a company of 40 developers stay on Warp's Business tier?
Not on Business, which stops at 25 seats. A group that size would need Enterprise, which has custom pricing, unlimited seats and advanced spend controls. You contact sales for it, so no price is published.
