Google Antigravity IDE Extensions Launch

• On 20 August 2026 Google introduced Antigravity Extensions for Visual Studio Code, Visual Studio, Zed, JetBrains IDEs and Xcode, positioned as lightweight editors-side companions to the agent-first Antigravity 2.0 app and CLI rather than full multi-agent hubs^[1]
• Install paths differ by editor: VS Code and Visual Studio through their marketplaces (search 'Google Antigravity'), JetBrains with one-click install from version 2026.2.1 onward across IntelliJ IDEA, PyCharm, WebStorm, GoLand, CLion and Rider, Zed with one-click install, and Xcode via the Intelligence settings panel in Xcode 27 beta 6 or later^[1]
• The New Stack describes what you get in the editor: agent conversations in a side panel, inline diff review, plan inspection and delegation of multi-step engineering tasks without moving a project into the desktop app, all on one Antigravity account with no separate sign-ins or licenses^[1]
• Maturity is uneven: The New Stack reports the VS Code extension is available now on macOS, Linux and Windows while the Visual Studio 2026 / .NET extension is in preview; Google's post adds that Enterprise support for JetBrains and Zed is in Preview^[1]

Notable features

• Individuals sign in with a Google account on any Antigravity plan including the free tier; enterprises sign in with Gemini Enterprise or Google Cloud project credentials, under Google Cloud terms that exclude customer data from foundation-model training and apply IAM and VPC Service Controls^[1][3]
• Same-day Google Cloud post: Antigravity and Android Studio can be enabled for users on eligible Gemini Enterprise Standard, Plus and Standard Emerging Market licences, with monthly project-level budget caps, pooled token quotas, opt-in overage billing with caps, usage metrics and one-toggle audit logging that captures prompts, agent responses and metadata^[3][4]
• Cost caveat from outside Google's post: The New Stack says the allowance is described as monthly but metered through a rolling seven-day pool, that everyone in the same edition, project and region draws on one pool, and that a nontrivial engineering task can use 150,000 to 200,000 tokens; per-user and team controls are only promised 'later this year'^[1][3]
• IT Brief adds that the rollout supports Workforce Identity Federation and Application Default Credentials so administrators can apply corporate identity standards^[4]
