Google Antigravity IDE lets you work with AI agents across an editor, terminal, and browser. To use it well, give an agent a bounded task and clear acceptance conditions, review its plan and changes, then verify the result yourself. Plans and diffs make work easier to inspect; they do not guarantee correct code.

What Antigravity IDE does

Google describes Antigravity as an agentic development environment that combines a full-featured editor with agents able to work across the workspace, terminal, and browser. You can work directly with an agent or delegate local tasks asynchronously. The editor also offers Tab completion, while artifacts can include Markdown plans, code diffs, architecture diagrams, images, and browser recordings. These are ways to understand and review work, not proof that an agent’s output is correct. Google Antigravity IDE overview

That combination changes the developer’s role: instead of treating each AI response as a code suggestion, you can delegate a defined piece of work and inspect the steps and results. Keep the scope small enough that you can judge whether the result meets your needs.

Use a reviewable workflow

1. Define the task and how you will accept it

Describe the change, the boundaries, and the evidence that would show it is complete. For example, ask for a form validation change, specify which fields and behavior must remain unchanged, and name the relevant tests or browser behavior to check. This is a practical way to make the request reviewable, not a required Google prompt format.

2. Ask for a plan before broad changes

For work that touches multiple files or has meaningful risk, ask the agent to outline its approach before it edits. Read the plan and clarify anything that exceeds the requested scope. Antigravity’s documented artifacts include plans and diff views that help make intended work visible. Google Antigravity IDE overview

3. Inspect edits and consequential actions

Review the diff for unrelated changes, unexpected file edits, and changes to behavior you intended to preserve. Inspect terminal commands and their output rather than assuming every command is safe or successful. Grant only the permissions needed for the task. Google’s enterprise guidance cautions against unrestricted auto-approval outside isolated development environments or disposable branches. Google Antigravity enterprise documentation

4. Verify the behavior

Run project-appropriate tests and check their output. If the change affects a user-facing experience, inspect it in a browser as well. Antigravity supports browser-use capabilities, and Google’s launch description presents browser testing as part of the agentic workflow; neither means an agent’s own verification is sufficient for every project.

5. Close the loop with specific corrections

Compare the result against the acceptance conditions you set. If a test fails or the browser behavior is wrong, give the agent the specific failure and ask for a targeted fix. Review the final diff and rerun relevant checks before treating the work as complete.

Choose an account and access path that fits

For individual use, Google’s extensions documentation says developers sign in with a personal Google Account, with model entitlements and quotas tied to that account. It lists integrations for Visual Studio Code, Visual Studio, JetBrains IDEs, Zed, and Xcode; enterprise support and preview status vary by integration. Check the live documentation for the editor you intend to use. Google Antigravity IDE extensions

The standalone Antigravity IDE overview says the IDE is not supported for enterprise customers and directs organizations needing enterprise configurations to Antigravity 2.0 or Antigravity CLI. Google’s enterprise documentation describes project-level logging of customer telemetry and model interactions for the selected license. Organizational use should therefore be evaluated against the current enterprise product and data terms, not assumed to have the same controls as an individual IDE account.

Understand plan limits and changing costs

Google’s plans page says model availability and rate limits vary by Google AI plan. It describes baseline Gemini model access and unlimited Tab completions; Pro and Ultra quotas refresh every five hours subject to weekly limits, while the baseline plan outside Pro and Ultra refreshes weekly. Task complexity affects quota use, and Google says rates may change. The page does not establish a stable numeric usage allowance suitable for treating as a general limit. Google Antigravity plans

Pro and Ultra users can enable AI-credit overages after the baseline quota is exhausted, and the documented controls allow overages to be turned on or off. The same plans page says AI credits use standard Gemini Enterprise consumption pricing and that BYOK (bring your own key/endpoint) and custom organizational tiers are not supported there. Check the current plan page for applicable terms before relying on a particular model, quota, or billing arrangement. Google Antigravity plans

Google’s pricing page currently presents an individual option at $0/month and describes Pro and Ultra as higher-access plans; it also describes organization access through Google Cloud. Pricing and eligibility can change, so confirm current details on the Google Antigravity pricing page.
