Antigravity

Introduction

Antigravity is Google's agent-first development platform, relaunched as Antigravity 2.0 at Google I/O 2026. First previewed at Google I/O November 2025 as an agentic IDE, it's now a platform for building, composing, deploying, and managing AI agents. The platform combines a desktop app, CLI, SDK, and web IDE — all powered by Gemini 3.5 Flash with 1M-token context — and introduces managed agent orchestration, subagent composition, and deep integration across Google's developer ecosystem.

The defining feature is the parallel agent canvas: multiple specialized agents work on different parts of a codebase simultaneously, then reconcile their changes under a single coherent plan. Antigravity 2.0 goes beyond coding — it's a platform for building custom agents that can be deployed as managed services, composed into workflows with subagents, and monitored from a dedicated desktop application.

The defining feature is the parallel agent canvas: multiple specialized agents work on different parts of a codebase simultaneously, then reconcile their changes under a single coherent plan.

Key Features

• Parallel agent canvas — multiple agents work concurrently on different files, tasks, or services, then merge results into a unified output
• Desktop app — new in 2.0, a native application for managing agents, workflows, deployments, and monitoring
• CLI — successor to Gemini CLI (sunset June 18, 2026), with full terminal-based agent orchestration
• SDK for custom agents — build your own agents with Antigravity's agent framework, defining tools, triggers, and behaviors
• Managed Agents — deploy agents as scalable services on Google Cloud with auto-scaling, monitoring, and logging
• Subagents — compose multiple specialized agents into a single workflow, with coordinated state and handoff
• Chrome DevTools integration — agents natively inspect the DOM, intercept network requests, debug console errors, and fix frontend bugs in real time
• Firebase MCP — conversational management of Firestore schemas, Cloud Functions, Authentication, and hosting
• Google Search grounding — every agent session has live web context via Google Search
• Gemini 3.5 Flash backbone — upgraded from 2.5 Pro at I/O 2026, delivering faster inference while maintaining 1M-token context windows
• Google AI Studio export — one-click export of prototypes from Google AI Studio directly into Antigravity agents
• Google Cloud integration — deploy agents to Cloud Run, connect to Cloud Storage, BigQuery, and Vertex AI
• MCP-extensible — connect any Model Context Protocol server for additional tools and data sources

Who It's For

Antigravity 2.0 targets developers and teams building within the Google ecosystem. It is ideal for:

• Full-stack developers on Firebase and Google Cloud who want AI-assisted development with deep platform integration
• Frontend engineers who value Chrome DevTools-level debugging in an agent context — a unique capability no competing platform offers
• Agent builders who want to create, compose, and deploy custom agents using an SDK rather than hacking together LLM chains
• Teams migrating from Gemini CLI who need a managed platform with monitoring, scaling, and subagent orchestration
• Google AI Studio power users who want a direct path from prototype to production agent

For developers outside the Google ecosystem — those who do not use Chrome , Firebase, or Google Cloud — the platform's unique value drops off. Antigravity is deeply opinionated about its stack.

How It Compares

Antigravity 2.0 sits in a different category from most coding agents:

• Cursor and Windsurf are IDE-native coding assistants. Antigravity is a full agent development platform with its own desktop app, SDK, and managed deployment. It competes at a higher level of abstraction.
• GitHub Copilot is code completion and chat embedded in editors. Antigravity is a multi-agent orchestration platform where agents build, deploy, and manage software — not just suggest lines.
• Claude Code is a terminal-first coding agent. Antigravity offers a desktop app, web IDE, and CLI side by side, plus managed deployment.
• Kiro and OpenHands are open-ended agent frameworks. Antigravity is more opinionated, more integrated with Google Cloud, and offers managed infrastructure.

The Chrome DevTools integration remains the single feature no competitor can match.

An Antigravity agent can open a browser, inspect the live DOM, identify a rendering bug, trace it to a React component, fix the source, and verify the result — all within one session.

Pricing

The Ultra tiers ($100/mo 5x, $200/mo 20x) include Antigravity credits that cover managed agent compute and subagent orchestration minutes. For most teams, the $100/mo Ultra 5x provides sufficient capacity; teams running multiple concurrent production agent workflows should consider the $200/mo Ultra 20x tier.

The Ecosystem Role

Antigravity 2.0 is the foundation for several Google products announced at I/O 2026:

• Gemini Spark — uses Antigravity agents under the hood for code generation and review
• AI Mode in Chrome DevTools — agents that interact with the DevTools panel conversationally
• Information Agents — deployed as managed Antigravity agents using Google Search grounding and MCP-connected data sources
• Daily Brief — personalized agent workflows that compile development status, deployment health, and team updates

This tight integration means Antigravity is not just a standalone product — it is the agent platform that powers Google's broader AI developer strategy.
