Google Antigravity
Google · Google's Agentic Development Platform: Desktop, IDE, CLI & SDK
Google Antigravity is Google's agent-first development platform for software engineers: a desktop command center for running coding agents in parallel, an agentic IDE, a terminal CLI, and a Python SDK built on the same agent harness. Free for individual developers, with higher limits through Google AI Pro and Ultra.
Best for
Developers who want to supervise several autonomous coding agents in parallel from a dedicated desktop app, with a free Gemini tier and Claude models on paid Google AI plans
Not ideal for
Teams that require an open-source client app, developers who want to bring their own API keys for more capacity, or anyone who needs precisely documented free-tier quotas before committing
Who it's for
Software engineers and teams who want to delegate multi-step coding work to parallel agents across desktop, terminal, and API
Capabilities
- Antigravity 2.0 desktop app manages multiple local agents in parallel, grouped by project across multiple folders
- Agents define and invoke subagents for focused subtasks, with live subagent status cards
- Automations run agents on demand or on a schedule, and /schedule sets one-off timers or cron wake-ups inside a conversation
- Browser-in-the-loop agents through Chrome with the /browser command, with each session recorded, plus a built-in browser in the side panel
- Plugin Marketplace for skills, MCP servers, rules, and subagents, including partner plugins such as Figma, Linear, Notion, and Stripe
- Remote Control to view and drive Antigravity desktop and CLI sessions from any web browser
- Local mode or New Worktree mode, where the agent works in an isolated Git worktree
- /plan drafts an editable plan before the agent writes any code
- JSON hooks and custom agents for customizing agent behavior, plus extensions for VS Code, JetBrains IDEs, Visual Studio, Xcode, Zed, and Eclipse
- Python SDK (Apache 2.0) with file I/O, code editing, shell execution, MCP servers, skills, and sub-agent delegation
Limitations
- Free Individual plan has a weekly quota and rate limit; Google does not publish exact quotas and says usage depends on capacity and task complexity
- The free plan centers on Gemini 3.8 Flash. Gemini 4 Argon needs Google AI Pro, Ultra, or Enterprise, and Claude Sonnet and Opus 5.5 need Ultra, Enterprise, or a paid (non-trial) Pro subscription
- No bring-your-own-key or custom endpoint option for extra capacity
- No open-source license is documented for the desktop app, IDE, or CLI; only the Python SDK is published under Apache 2.0
- The Python SDK is a local runtime; for a hosted agent, Google points to the separate Antigravity Agent in the Gemini API, which is still in preview
- Rapid release cadence, including breaking tool changes in the Gemini API managed agent between preview versions
Use cases
- Running several coding agents in parallel on separate features, each in its own Git worktree
- Having an agent test and debug a frontend by driving Chrome with /browser
- Scheduling a nightly agent run to triage failing tests or update dependencies
- Reviewing and editing a /plan before letting the agent implement a larger change
- Prototyping a custom coding or automation agent in Python with the Antigravity SDK
- Moving an existing Gemini CLI workflow to the Antigravity CLI

Free tier limits: The Individual plan uses Gemini 3.8 Flash with a weekly quota and rate limit. Google does not publish exact quotas and says how far they go depends on capacity and how much work each task takes.
Note: Pro and Ultra benefits come through Google AI subscriptions, priced outside the Antigravity pricing page. When the baseline quota runs out, Pro and Ultra users can spend purchased AI credits at Gemini Enterprise consumption pricing, controlled by an AI Credit Overages setting. Bring-your-own-key is not supported. Business access is billed through Google Cloud under the Google Cloud Terms of Service.
Technical specs
Available models
Google Antigravity vs. competitors
Google Antigravity vs. Cursor
Cursor centers the editor and runs background agents in the cloud that return pull requests; Antigravity pairs an IDE with a separate desktop app for supervising local agents, and extends the same harness to a CLI, SDK, and Gemini API.
Google Antigravity vs. Claude Code
Claude Code is Anthropic's coding agent across terminal, IDE, and desktop; Antigravity is Google's multi-surface platform whose paid Google AI Pro and Ultra plans also offer Claude Sonnet and Opus 5.5 alongside Gemini models.
Google Antigravity vs. Windsurf (now Devin Desktop)
Devin Desktop (formerly Windsurf) is a single agentic editor; Antigravity splits the workflow into an agent manager app, an IDE, and a CLI that share one runtime.
Google Antigravity vs. OpenCode
OpenCode is an open-source terminal coding agent you can point at many model providers; Antigravity offers a Google-curated model list, and only its Python SDK carries a documented open-source license.
Frequently asked questions
What is Google Antigravity?
Antigravity is Google's agentic development platform. It includes Antigravity 2.0 (a desktop command center for running agents in parallel), the Antigravity IDE, a terminal CLI, IDE extensions, and a Python SDK, all built on the same agent runtime.
Is Google Antigravity free?
Yes for individuals. The Individual plan is $0/month with unlimited Tab completions and Command requests, Gemini 3.8 Flash as the agent model, and a weekly rate limit. Google AI Pro and Ultra add more models, higher limits that refresh every five hours, and AI credits for usage beyond the quota. Organizations use the Business plan through Google Cloud: seats from $30 per user per month for eligible Gemini Enterprise customers, a pay-as-you-go plan with no seat fee, or consumption-based API pricing.
Which models does Antigravity support?
It depends on the plan. Free and Google AI Plus accounts get Gemini 3.8 Flash. Google AI Pro and Ultra add Gemini 4 Argon and Claude Sonnet and Opus 5.5 (on Pro, Claude needs a paid subscription rather than a trial), and Enterprise also gets Gemini 3.7 Flash, Gemini 3.6 Flash, and Gemini 3.1 Pro. Claude Sonnet and Opus 4.6 and GPT-OSS 120B, earlier offered on the free plan, are marked for removal on November 2, 2026. Each model offers Low, Medium, or High thinking levels where supported.
What is the difference between Antigravity 2.0 and the Antigravity IDE?
Antigravity 2.0 is a standalone, agent-first desktop app, separate from the IDE, built for managing multiple local agents across projects. The Antigravity IDE is the editor-centered product. Google lets existing IDE users keep the IDE while installing 2.0, so both can run side by side.
Is Google Antigravity open source?
No open-source license is documented for the desktop app, IDE, or CLI. The Antigravity SDK for Python is released under the Apache 2.0 license and installs with pip install google-antigravity.
Google Antigravity vs Cursor: what is the difference?
Cursor is a VS Code-based editor with agent mode and cloud background agents. Antigravity offers a separate agent-first desktop app for running local agents in parallel alongside its IDE, plus a CLI, a Python SDK, and a hosted agent in the Gemini API.

FreemiumAbout Google Antigravity
Antigravity began as an agentic IDE in November 2025 and has grown into a product family that shares one agent runtime. Antigravity 2.0, a standalone desktop app separate from the IDE, is the agent-first surface: conversations are grouped into projects that can span several folders, agents spin up subagents for focused subtasks, Automations run agents on demand or on a schedule, JSON hooks let you intercept agent behavior, a plugin Marketplace adds skills, MCP servers, rules, and subagents, and a /browser command puts Chrome in the loop for frontend work. Agents can run in your working folder or in an isolated Git worktree, and Remote Control lets you drive desktop and CLI sessions from any web browser. The same harness powers the Antigravity CLI (Google's consolidation path from Gemini CLI), extensions for VS Code, JetBrains IDEs, Visual Studio, Xcode, Zed, and Eclipse, an Apache 2.0 Python SDK for building custom agents, and a managed Antigravity agent in the Gemini API. The Individual plan is $0 with Gemini 3.8 Flash as the agent model and a weekly rate limit. Google AI Pro and Ultra add Gemini 4 Argon and Claude Sonnet and Opus 5.5, higher limits that refresh every five hours, and AI credits for overage. Google's model table marks Claude Sonnet and Opus 4.6 and GPT-OSS 120B, which the free plan used to include, for removal on November 2, 2026. Organizations buy a Business plan through Google Cloud, with seats from $30 per user per month for eligible Gemini Enterprise customers, a pay-as-you-go plan with no seat fee, or consumption-based API pricing. The tradeoffs are a fast-moving release cadence with frequent changes, quotas that Google does not publish as numbers, third-party models only on paid plans, and the fact that only the SDK, not the desktop apps or CLI, carries a documented open-source license.
