Google Antigravity Comes to VS Code: Agentic Coding Without Leaving Your Editor

If you've tried an "agentic" AI coding tool recently, there's a good chance it asked you to switch editors entirely. Google's own agent-first IDE, Antigravity, launched in November 2025 with exactly that trade-off: full agentic power, but only inside its own dedicated desktop application. That trade-off just went away. Google has shipped Antigravity extensions for VS Code, Visual Studio, JetBrains, and Zed , bringing the same agent, the same review workflow, and the same account into the editor you've already spent years configuring exactly the way you like it.

By the end of this article, you will be able to: Explain how the extension relates to the full Antigravity 2.0 desktop app and the agy CLI Install and authenticate the extension inside VS Code Work through the agent side panel, implementation plans, and walkthroughs Configure the permission engine so the agent only does what you approve Lock down its browser subagent so it never touches your personal Chrome data New to Antigravity generally? Start with Google's own primer: Antigravity 2.0 Overview Prerequisites To follow along hands-on, you'll need: VS Code version 1.90 or later, on macOS, Linux, or Windows A Google Account on any Antigravity plan (the free tier is enough), or an enterprise account enabled for Gemini Enterprise About five minutes for the first-time sign-in and backend install You can also read this purely as an architecture and workflow walkthrough; every step is explained, not just shown. 1. Where the Extension Fits in Antigravity's Architecture It helps to know there are actually three doors into the same house: [ Antigravity 2.0 ] ── the full desktop app, a dedi
