What's Google Antigravity 2.0? Here's What the Agent Harness Actually Changes for Developers.

Google introduced Antigravity 2.0 at I/O 2026 as an agent-first platform built on one shared harness across desktop, CLI, SDK, and IDE surfaces.

It supports parallel agents, background scheduled tasks, plugin-style extensions, and Managed Agents in the Gemini API for stateful automation.

The move signals a shift away from editor-bound assistance and older Gemini CLI and IDE extensions toward persistent, shared agent infrastructure.

For developers, this could reshape how teams orchestrate AI workflows, CI pipelines, and deployment automation across products like Google AI Studio, Android, and Firebase.
