Google Antigravity is Google’s tool for building software by directing AI agents instead of writing code. You describe what you want, and an agent works in a folder on your computer: it creates and edits files, runs the commands a developer would run, opens your app in a browser to check it, and reports back with screenshots and a plain-language walkthrough. Google’s own line is that it lets “anyone build in the agent-first era.” Yes, someone who cannot code can use it. It is free to start with a personal Google account, it runs on Mac, Windows and Linux, and it is the same kind of tool as Claude Code and Codex rather than a website builder like Lovable or Base44. The catch is the same as with those two: it hands you files, not a hosted product.
What Antigravity is, and where it came from
Google released Antigravity on November 18, 2025 as a free public preview: a code editor with an agent inside, a “manager” screen for running several agents at once, and control of a Chrome browser so the agent could test its own work. In May 2026 it split into a family. Antigravity 2.0 is a standalone desktop app built around the agents rather than an editor. The original Antigravity IDE, an editor with the agent in a side panel, still exists and is still what Google recommends for developers. The Antigravity CLI is the terminal version, and it replaced Gemini CLI when Google stopped serving that to individual accounts on June 18, 2026.
For someone who does not write code, the difference between 2.0 and the IDE is small. Both work on a Project, Google’s word for the folder or folders the agent may touch, and both give the agent a terminal and a browser. The IDE shows you the code as it changes. Antigravity 2.0 shows you the plan, the progress and the artifacts: the walkthrough, screenshots and browser recordings it produces. If you never intend to read code, 2.0 is the more comfortable room.
The models are Google’s Gemini family, and Google’s models page also lists a few from Anthropic and OpenAI on the individual plans.
What it costs, in shape
There is a free plan for individuals. You sign in with a personal Google account; Google’s FAQ says work accounts may not get in, and under-18s are not allowed. Google describes the free quota as “basic weekly rate limits”: a bucket of agent work that refreshes once a week. The paid Google AI subscriptions get a larger bucket that refreshes every five hours until a weekly cap, and they can buy AI credits to keep going past it.
The meter counts the agent’s work, not your messages. In Google’s words, how far a quota goes “depends on the amount of work done by the agent, which can differ from prompt to prompt.” Asking for a whole app, then asking it to fix the whole app, can spend a weekly bucket in an afternoon, and on the free plan that means a week of waiting. Lovable’s credits are gone when they are gone. Antigravity’s quota comes back, but slowly.
What it does not do
Antigravity hosts nothing. While the agent builds, the app exists only in your folder, and getting it onto the internet means a hosting service you choose and set up separately. It ships no database and no login screen. Google’s docs describe those as things the agent can set up for you in Google’s own cloud services, Firebase and Cloud Run among them, and each of those is a separate account with its own bill. The agent can open your app in Chrome and click through it, but the app it clicks through still lives on your computer.
If the wall you hit in a browser builder was “I want my app where people can use it,” Antigravity alone does not move it. If it was “the builder will not change this” or “I want to own the files,” it does.
How to install it on Windows or a Mac
The only download is Google’s own, at antigravity.google/download. Other sites offer an “Antigravity download for Windows”; they are not Google’s, and that address is the only one to use.
On Windows, which needs Windows 10 64-bit or later:
- Go to antigravity.google/download and pick the Windows download, x64 unless your PC is ARM.
- Run the installer. If it asks whether to Replace an existing copy, say yes.
- Say no when setup offers to install the Antigravity IDE as well; you can add it later.
- Open Antigravity and sign in with a personal Google account.
On a Mac, which needs macOS 12 Monterey or later:
- Go to antigravity.google/download and pick Apple Silicon or Intel, whichever your Mac is.
- Open the downloaded .dmg and run the installer. Say yes if it asks to Replace an existing copy.
- Say no when setup offers to install the Antigravity IDE as well; you can add it later.
- Open Antigravity and sign in with a personal Google account.
Antigravity vs Claude Code vs Codex, for someone who can’t code
All three do the same job in the same way. Each reads, edits and runs files in a folder on your computer from plain-language instructions. Each has a desktop way in that needs no terminal, plus a terminal version and an editor extension.
The differences are about money and about whose account you already have. Antigravity is free with a Google account and metered weekly. Codex comes with every ChatGPT plan, free included, metered in five-hour windows with weekly limits on top. Claude Code needs a paid Claude plan, and its allowance, shared with the Claude chat app, resets on a rolling five-hour window with weekly limits on top. Antigravity reorganized itself in May 2026, so tutorials from before then show a different program. None of the three hosts, and none includes a database or a login.
The choice, then, is the account you already pay for and the tool you can open tonight.
You can learn more, and get the full prompts and the decision tables, in our course, starting from You’ve Outgrown Lovable. The first lesson is free, no card.
In the next ten minutes, decide which wall you are at. If you want a hosted app with no decisions to make, stay with a browser builder. If you want the files, download Antigravity from Google’s page, sign in, make an empty folder on your Desktop, and ask for the smallest thing you actually want, in plain words.
