Google Antigravity 2.0 — Standalone Agent-First Desktop App, Go-Based CLI, and SDK Replace Gemini CLI Ahead of June 18 Sunset
At I/O 2026, Google relaunched Antigravity as a standalone agent IDE plus a new Go CLI and SDK. The Gemini CLI and Code Assist IDE extensions stop serving Pro and Ultra users on June 18.

Google's I/O coding-agent push: one desktop app, one terminal, one SDK, and a hard deadline to migrate off Gemini CLI.

What is it?
Antigravity 2.0 is a standalone desktop application that hosts multi-agent workflows. Alongside it, Google shipped a Go-based Antigravity CLI for terminal users, an SDK for hosting custom agents, and confirmed that Gemini CLI and Gemini Code Assist IDE extensions stop serving Pro and Ultra users on June 18, 2026.
How does it work?
The desktop app orchestrates subagents in parallel, runs scheduled background tasks, and integrates with Google AI Studio, Android, and Firebase. The CLI shares the same agent harness as the desktop so improvements ship in both. The SDK exposes that harness for self-hosted custom agents tuned for Gemini models. All three are powered by Gemini 3.5 Flash, which Google says was co-developed with Antigravity. Enterprise customers on Code Assist Standard or Enterprise keep their Gemini CLI access.
Why does it matter?
Antigravity is Google's direct answer to Claude Code and OpenAI Codex. The Gemini-CLI-to-Antigravity-CLI cut-over forces every individual Gemini CLI user onto the new platform inside 30 days, and the pricing reshuffle (a new $100 Ultra tier and a cheaper $200 Premium tier) is aimed at developers comparing tiers against Anthropic and OpenAI.
Who is it for?
Gemini API users, coding-agent enthusiasts, and teams currently on Gemini CLI or Code Assist
