Getting access

Antigravity is free while it is in public preview. Everything below is Google's to give and Google's to change — checked 29 August 2026.

Read this before anything else

This site cannot sell you Antigravity, and will never ask for a credential.

There is no account here, no checkout, no form and no field that would legitimately ask for a Google password, a payment card or an API key. If a page claiming to be this one asks you for any of those, it is not this site. Downloads come from one place: antigravity.google/download.

First run

Four steps from download to a task you can trust

Condensed from Google's getting-started documentation, with the one piece of advice it does not give: read the plan before the diff.

Step 01

Get it from Google

Downloads are at antigravity.google/download and nowhere else. If the installer offers Keep Both or Replace over an existing install, Replace is the documented choice.

Step 02

Draw the boundary

Create a project — the folder icon with a plus — and add the local folders or Git repositories the agents may touch. That set is the limit of what they can read or change, so make it deliberately narrow the first time.

Step 03

Choose how a run lands

Local Mode edits your folder directly. New Worktree Mode puts the run in its own Git worktree. For a first real task, take the worktree.

Step 04

Describe an outcome, then read the plan

Type the goal rather than the mechanics. When the implementation plan comes back, read it before the diff — it is the cheapest place to catch a run that understood the wrong problem.

The five-hour meter is the detail most people meet by surprise. Limits refresh on that cycle and scale with how much work a request represents, so a single large refactor can consume more of a window than an afternoon of small questions.
