Google Antigravity launched in November 2025 as an AI-powered code editor, then relaunched as Antigravity 2.0 at Google I/O in May 2026 as a full standalone agent-first development platform: a desktop app for orchestrating multiple coding agents at once, a CLI (which absorbed and replaced the earlier Gemini CLI), an SDK, a Managed Agents API, and an enterprise deployment path.

The desktop app lets developers run multiple agents in parallel, design custom subagent workflows, and schedule tasks to run automatically in the background rather than working through one task at a time in a single chat window. It's powered by Gemini 3.5 Flash, which Google says outperforms its own Gemini 3.1 Pro on most benchmarks while running roughly four times faster, and includes live voice transcription via Gemini Audio models.

Antigravity includes a free tier for individual use. Higher usage requires a Google AI Pro or the new AI Ultra plan, which costs $100/month and provides 5x the usage limits of the standard Pro tier.
