Google Antigravity in 2026: IDE, Antigravity 2.0, CLI, Pricing and Limits Explained

Google Antigravity is Google's agentic development platform, and in September 2026 it ships as five surfaces: the Antigravity IDE, the agent-first Antigravity 2.0 desktop app, the Antigravity CLI (agy), extensions for VS Code, Visual Studio, JetBrains, Zed and Xcode, and a Python SDK. Every surface is free to use with a Google account under a weekly rate limit; Google AI Pro ($19.99/month) and Google AI Ultra (from $99.99/month) raise the limits, refresh them every five hours, and add paid overage credits. If you only remember one thing: Antigravity is the cheapest way to try a multi-agent coding workflow in 2026, but Google does not publish hard quota numbers, so heavy users should plan around the limits rather than assume them.

Last updated: September 28, 2026. Every price, model, and limit below was checked against antigravity.google, the Antigravity docs, and Google One on that date. This page originally reviewed the November 2025 preview; it has been rewritten as the 2026 guide, and the preview notes are kept at the end.

Newer model context: Gemini 4 Argon now makes Antigravity's harness design more important, because the model's long-output promise only helps if the agent surface handles permissions, checkpoints, and review cleanly.

The Antigravity family at a glance#

Antigravity launched in November 2025 as a single VS Code-style IDE with an "Agent Manager" bolted on. On May 19, 2026 Google introduced Antigravity 2.0, a separate desktop app with no IDE at all, and in the same wave replaced Gemini CLI with Antigravity CLI (Gemini CLI stopped serving requests on June 18, 2026). August added IDE extensions and remote control. The current lineup from the download page:

Google's own recommendation in the 2.0 announcement is to "dual-wield" Antigravity 2.0 with your IDE of choice. That is the mental model for 2026: agents in 2.0 or the CLI, editing and debugging in an IDE.

Antigravity 2.0: the agent-first desktop app#

Antigravity 2.0 is where Google is putting its weight. Per the launch post, it groups conversations into Projects that can span multiple folders with their own settings and permissions, instead of tying one agent to one repository. The agent can spin up dynamic subagents for focused subtasks, run tasks asynchronously, and be intercepted with JSON hooks. Scheduled Tasks trigger agents on a cron.

The getting started guide documents two ways to boot an agent: Local Mode (works directly in your folders) and New Worktree Mode (works in an isolated Git worktree). It also lists the slash commands worth learning first:

Since launch Google has added Custom Agents (August 12, Markdown-defined specialist agents with scoped skills and command policies) and Remote Control (August 21, drive sessions on another machine from a browser, with push notifications).

Antigravity CLI: the terminal surface#

The CLI is the successor to Gemini CLI and shares its agent harness with 2.0. Install it with the official script from the docs:

# macOS / Linux
curl -fsSL https://antigravity.google/cli/install.sh | bash

# Then, inside a project
agy

On Windows PowerShell the installer is irm https://antigravity.google/cli/install.ps1 | iex. The binary lands at ~/.local/bin/agy on macOS and Linux. First launch walks you through a color scheme, a rendering mode (alt-screen or inline), and a workspace trust prompt before the agent indexes your files.

If you are coming from Gemini CLI, our Gemini CLI to Antigravity CLI migration guide covers config, MCP, and extension changes step by step. For how agy stacks up against the other terminal agents, see Antigravity CLI vs Claude Code vs Codex.

Antigravity IDE and the new extensions#

The standalone Antigravity IDE still exists (v2.5.5 today), but its role has narrowed. Google said in May that an upcoming release would remove the Agent Manager from the IDE, "turning the IDE into a purely agent-powered IDE," with multi-agent work moving to 2.0.

The bigger change is that you no longer need Google's editor at all. On August 20, 2026 Google shipped Antigravity extensions for Visual Studio Code, Visual Studio, JetBrains IDEs (2026.2.1 and later), Zed, and Xcode (27 beta 6 or later). Individuals sign in with any Antigravity plan, including the free tier; enterprise teams sign in through Gemini Enterprise or a Google Cloud project, with JetBrains and Zed enterprise support still in preview.

Antigravity pricing in 2026#

Antigravity itself has no price tag. What you pay for is quota, through Google's consumer AI plans or Google Cloud. From the pricing page and Google One, verified September 28, 2026:

Two things the pricing page will not tell you until you read the plans doc: there is no bring-your-own-key or bring-your-own-endpoint option for extra capacity, and there are no contract-based organizational tiers for the consumer product.

Antigravity limits: how the quota actually works#

Google does not publish a request count. The plans doc describes the tiers qualitatively:

The important sentence is this one: the limits "are correlated with the amount of work done by the agent, which can differ from prompt to prompt." A quick, well-scoped task costs little; an open-ended refactor that runs for an hour costs a lot. Google also notes the limits exist "primarily" to the degree it has capacity and may change.

What happens when you hit the wall depends on your plan. Pro and Ultra users can buy AI credits and set "AI Credit Overages" to Always (spill into credits automatically, switching back when the quota refreshes) or Never (wait for the refresh). Credits are consumed at Gemini Enterprise consumption pricing. Free users simply wait for the weekly reset.

The in-app usage panel shown on the models page meters Gemini models and Claude and GPT models separately, each with a weekly and a five-hour gauge. In practice that means running out of Gemini quota does not stop you from switching to a third-party model, and vice versa.

Which models Antigravity supports#

From the models doc on September 28, 2026:

Nano Banana 2 powers the built-in image tool for UI mockups and diagrams and is not user-selectable. Note what is missing: the third-party options are a generation behind the newest Anthropic models, and Enterprise is Gemini-only. If you need the latest Claude models for coding, that is a real reason to look at Claude Code or Cursor instead.

Who should use Antigravity in 2026#

• Students, hobbyists, and anyone cost-sensitive. No other major agentic platform gives you a working multi-agent setup with frontier Gemini models for $0.
• Gemini CLI refugees. The CLI is the official path forward, and the migration is well documented.
• Teams already on Google Cloud. The organization plan brings Antigravity 2.0 and the CLI under Google Cloud terms, and per the extensions announcement enterprise sign-ins respect your IAM policies and VPC Service Controls, with no training on your data.
• Developers who want to keep their editor. The VS Code, JetBrains, Zed, and Xcode extensions make Antigravity an add-on rather than a switch.

Skip it, or pair it with something else, if you need the newest Claude models, predictable published quotas, or bring-your-own-key billing.

The November 2025 preview, for the record#

The original version of this post reviewed the public preview that launched in November 2025. At the time, Antigravity was a single VS Code-style IDE built by a team that originated at Windsurf, with an Agent Manager inbox for coordinating agents across workspaces.

The preview offered a planning mode (review and comment on a plan before execution) and a fast mode (start working immediately), automatic browser testing of the app it built, and Nano Banana image generation inside the editor. Much of that survived: planning became artifacts you can comment on in 2.0, browser testing became the explicit /browser command, and image generation now runs on Nano Banana 2.

FAQ#

Is Google Antigravity free?#

Yes. As of September 28, 2026 the Individual plan costs $0 and includes agent model access, unlimited Tab completions, unlimited command requests, and a weekly rate limit. Google AI Pro ($19.99/month) and Ultra (from $99.99/month) raise the limits and refresh them every five hours.

What are Antigravity's rate limits?#

Google does not publish fixed numbers. Free users get a quota refreshed weekly; Pro and Ultra get quotas refreshed every five hours, capped by a weekly limit. Limits scale with how much work the agent does, not with prompt count, and Gemini models are metered separately from Claude and GPT models.

What happens when I hit the Antigravity limit?#

On the free plan you wait for the weekly refresh. On Pro or Ultra you can buy Google AI credits and set AI Credit Overages to Always, which spends credits at Gemini Enterprise consumption pricing until your quota refreshes. There is no bring-your-own-key option.

What is the difference between Antigravity 2.0 and the Antigravity IDE?#

Antigravity 2.0 is an agent-first desktop app with no code editor, built for running and scheduling multiple agents across Projects. The Antigravity IDE is a traditional editor with agents built in. Google recommends using 2.0 alongside whichever IDE you prefer, and now ships extensions for VS Code, JetBrains, Zed, Visual Studio, and Xcode.

How do I install the Antigravity CLI?#

On macOS or Linux run curl -fsSL https://antigravity.google/cli/install.sh | bash, then run agy inside a project. On Windows PowerShell use irm https://antigravity.google/cli/install.ps1 | iex. The CLI replaced Gemini CLI, which stopped serving requests on June 18, 2026.

Can I use Claude models in Antigravity?#

Yes, on Free, AI Plus, AI Pro, and AI Ultra: the models page lists Claude Sonnet 4.6 and Claude Opus 4.6 (thinking), plus GPT-OSS-120b. Enterprise is Gemini-only. The newest Claude releases are not offered.

Is Antigravity better than Cursor or Claude Code?#

It depends on what you optimize for. Antigravity wins on free usage and Google Cloud integration. Cursor wins on model choice and editor polish. Claude Code wins on terminal-first workflows with the newest Claude models. See our Antigravity vs Cursor comparison for a full breakdown.
