Google Launches Antigravity 2.0: Agent-First Dev Platform with Desktop App, CLI, and Managed Agents API
Google launched Antigravity 2.0 at I/O 2026 — a standalone agent-first development platform with a desktop app, CLI, and SDK for orchestrating multi-agent workflows. Simultaneously, Google introduced Managed Agents in the Gemini API: a single API call spins up a fully sandboxed Linux agent running the Antigravity harness, supporting persistent multi-turn sessions and custom AGENTS.md/SKILL.md definitions. During the keynote demo, Antigravity 2.0 built a working OS framework in ~12 hours using 93 parallel sub-agents for under $1,000.
