Google Antigravity: is Google's agent platform worth it?

• What you will learn: what Google Antigravity is, how to access it and how to use it day to day.
• Who it is for: people starting with vibe coding who have a Google account.
• Outcome: Antigravity working and a simple flow to create, review and publish.
• Analysis basis: official documentation, no own performance testing.

Google Antigravity is Google's programming agent platform. You describe what you want, and the agents plan, write and test the code.

According to the official documentation, it appears in several forms: a desktop app, a CLI called agy, extensions for editors like VS Code and JetBrains, and a Python SDK.

What you need before you start

• A Google account.
• A test project in Git.
• Optional: VS Code, if you want to use the extension.

How to access: start with your Google account

Download the app or install the extension from the links in the official documentation. When you open it, sign in with your Google account.

There is an individual free tier and larger tiers tied to Google AI plans. Each has weekly limits and five hours of usage. Check the official page for what applies to your account.

What it offers

• Several models: Gemini, plus Claude and GPT models.
• Subagents: helper agents that work in separate copies of the project, the git worktrees.
• MCP: connection to external tools, such as databases and browsers.
• Skills: custom instructions you teach the agents.
• Permissions: you decide what the agent can do without asking.

Is Google Antigravity good? Is it worth it?

If you have a Google account and want to start for free, it is a great starting point. The free tier lets you test the agents at your own pace.

Usage limits are the point to watch. On large projects, you can hit the limit before the end of the day.

App, extension or CLI: which to use?

The desktop app is the simplest way to start: you chat with the agents in its own window. CLI agy runs in the terminal and works well for those who already work in VS Code. See the step by step in how to use Antigravity CLI in the VS Code terminal.

Using with other agents

Antigravity does not need to work alone. bridgecode is an extension you install in VS Code or Antigravity IDE and that accepts Antigravity as an agent.

This way you combine Antigravity with Claude Code, Codex or OpenCode, each with its own account. In Claude Code, for example, you sign in with a Pro or Max subscription, as shown in our guide on how to install and use Claude Code in VS Code.

Practical flow: create, review and publish

1. Create

Write the request as if you were talking to a colleague:

Request: "Create a one page site for a cafe, with menu and map. Before you change anything, show me the plan."

Read the plan, approve it or ask for adjustments. Then the agent writes the code and runs the project to check.

2. Review

Look at the changes before accepting them. The editor's Source Control tab shows each line changed.

Also ask: "Review what you did and explain in simple language." If something breaks, paste the error in the chat and ask for a fix.

3. Publish

Git is the project's version history. A pull request, or PR, is a request to merge changes into the main project after review.

1. Ask: "Create a branch called site-cafeteria and make a commit with a clear message."
2. Ask: "Push the branch to GitHub and open the PR."
3. Review the PR on GitHub and merge it.

The same flow in bridgecode, with separate roles

In bridgecode, Antigravity can take on one role on the team while other agents handle the rest:

• Planner: reads the request and breaks it into small tasks.
• Executor: writes the code for each task.
• Reviewer: checks everything and flags errors before the PR.

Each agent works on a separate copy of the project, so one does not interfere with the other. You approve the plan at the start and the PR at the end.

For example, Antigravity executes and Claude Code reviews. This also helps split usage across each account's limits.

Common mistakes and how to avoid them

Granting all permissions

Start by asking for approval for commands. Grant access gradually, once you trust the flow.

Ignoring limits

Track how much you've already used. Break large tasks into small parts.

Thinking it's just another editor

Antigravity is focused on agents. Use plan mode and review before accepting.
