What Is Google Antigravity? Google's Agent-First Coding Tool Explained
Google Antigravity is an agent-first development platform: a desktop IDE, a CLI and an SDK built around Gemini models, where you dispatch AI agents to plan, code and test while you review their work. What it does, how it differs from a normal editor, whether it's free, and who it suits.
Google Antigravity is Google's platform for building software with AI agents. Instead of an editor with an AI chat box bolted on, it's built around the idea that you dispatch agents to do work — plan a feature, write the code, run it, test it in a browser — and you review what they produce.
Details as of October 2026. Antigravity ships updates frequently; check antigravity.google for the current state.
The pieces
- A desktop IDE — a heavily modified VS Code — with an agent built in.
- An agent manager, where you start several agents in parallel across projects and watch their progress.
- A CLI (
agy) for working from the terminal. In 2026 Google folded its Gemini CLI into Antigravity. (What Is Gemini CLI?) - An SDK and API access for running the Antigravity agent from your own code.
It launched in November 2025 alongside Gemini 3 and is built mainly around Gemini models, with some other models available.
How it feels to use
The big idea is artifacts. Rather than scrolling through raw logs to see what an agent did, you get reviewable outputs: a task list, an implementation plan, screenshots, browser recordings of the agent testing your app. You comment on those like you'd comment on a colleague's work, and the agent adjusts.
Agents can use the editor, a terminal and a built-in browser, so they can check their own work — start the dev server, click through the page, notice the button doesn't work.
Recent versions added plan review before code is written, plugin management with a marketplace, and multi-agent features for bigger jobs.
Is it free?
There's a free individual tier with usage limits that reset weekly. Higher limits come with Google's paid AI plans, and there are business and enterprise options. Exact allowances change, so check the current plan page.
Antigravity vs Claude Code vs Cursor
| Antigravity | Claude Code | Cursor | |
|---|---|---|---|
| Made by | Anthropic | Anysphere | |
| Main models | Gemini | Claude | Many providers |
| Core idea | Agent manager + artifacts | Agent in your existing tools | AI-first editor |
| Free tier | Yes | No | Yes, limited |

Who it suits
- People who like delegating whole tasks and reviewing results rather than pair-programming line by line.
- Teams already using Google's AI plans or Google Cloud.
- Anyone who wants to try agentic coding on a free tier before paying.
As with any agent, the basics still apply: keep your code in git, review what the agent changes, and don't give it access to production credentials. (How to Review AI-Generated Pull Requests)
The summary
- Antigravity is Google's agent-first coding platform: IDE, agent manager, CLI and SDK.
- It runs mainly on Gemini and shows agent work as reviewable artifacts.
- There's a free tier with weekly limits.
EasySpawn takes a different route: a persistent server with Claude Code built in, next to your app and database, reachable from any device. See how it works or join the waitlist.
