Antigravity CLI succeeds Gemini with background agents
Google's new Antigravity CLI (agy) is a Go-based terminal interface for agent orchestration, featuring asynchronous background tasks and a built-in browser skill for web-based automation. It officially replaces the legacy Gemini CLI, which is scheduled for sunset in June 2026.
Google is pivoting from simple chat interfaces to a robust agentic architecture that treats the terminal as a primary orchestration surface.
- –The shift to Go significantly improves startup speed and resource efficiency over its predecessor.
- –Background subagents allow for non-blocking multi-step reasoning, enabling developers to run long-running tasks like security audits while they continue to code.
- –A built-in browser skill bridges the gap between CLI-based development and web-based documentation and testing.
- –The shared agent harness ensures consistency between the CLI, the Antigravity 2.0 desktop app, and the IDE.
