Google Antigravity 2.0 vs the Antigravity IDE

Google released Antigravity 2.0 alongside a command-line interface (CLI) and a software development kit (SDK) at Google I/O on May 19, 2026, while maintaining the Antigravity IDE for developers who write code manually.

Run Antigravity 2.0 alone if agents make all your file edits. Keep the IDE alongside it if you edit files by hand.

Antigravity 2.0 vs the Antigravity IDE

Google Antigravity 2.0 is a standalone desktop application dedicated to managing autonomous agents, whereas the Antigravity IDE is a full code editor designed for direct software development.

While the 2.0 desktop application replaces the role of the IDE's Agent Manager, Google did not deprecate the IDE and explicitly recommends that software engineers keep both environments installed.

Google launched the original Antigravity IDE on November 18, 2025, offering a code editing surface alongside an embedded Agent Manager. At Google I/O on May 19, 2026, Google introduced Antigravity 2.0 as an independent workspace focused exclusively on agent orchestration.

Because Antigravity 2.0 contains no code editor, developers working in 2.0 rely on autonomous agents to write, inspect, and modify files on disk rather than editing lines manually.

• Google said the Agent Manager will be removed from the IDE in an upcoming release.
• Gemini 4 Argon runs in the 2.0 desktop app and the CLI, but not in the Antigravity IDE.

Keep the Antigravity IDE or Run Antigravity 2.0 Alone

Google recommends that software developers keep the Antigravity IDE installed alongside Antigravity 2.0 rather than treating the standalone application as a replacement.

Developers who write code directly need an editor canvas. For those engineers, running the Antigravity IDE alongside Antigravity 2.0 preserves local editing while delegating tasks to the 2.0 agent runtime.

Conversely, users who oversee autonomous workflows without directly writing code can run Antigravity 2.0 alone.

Engineers who prefer external editors like Visual Studio Code, Visual Studio, Zed, JetBrains (version 2026.2.1 and newer), or Xcode (version 27 beta 6 and newer) can use the official Antigravity IDE extensions released on August 20, 2026. These extensions function across all tiers, including the free Individual plan, bringing Antigravity agent capabilities into an established development environment.

Google announced that the Agent Manager will be removed from the Antigravity IDE in an upcoming release. As of October 2026, this removal has not shipped, but developers should plan for agent supervision to live inside the 2.0 desktop application or the CLI.

• Keep both tools if you write code manually and want autonomous agent execution in a separate window.
• Run Antigravity 2.0 exclusively if your work consists entirely of directing agents without manual typing.
• Stay in your existing editor if you use VS Code, Visual Studio, Zed, JetBrains, or Xcode by installing the Antigravity extension, which works on every plan including the free one.

Tools and Infrastructure Launched at Google I/O 2026

At Google I/O on May 19, 2026, Google expanded the Antigravity ecosystem beyond the desktop app by launching a command-line interface, a software development kit, and a restructured subscription model.

The Antigravity CLI, executed via the command agy, provides an agent runtime written in Go. agy uses the same agent harness and settings as the 2.0 desktop app, and CLI conversations open in 2.0. The Google Antigravity CLI guide covers terminal setup and automation commands.

The CLI directly succeeds Gemini CLI for consumer accounts. On June 18, 2026, Gemini CLI and Gemini Code Assist IDE extensions ceased serving requests for Google AI Pro, Google AI Ultra, and free individual users, per the Google Developers Blog. Gemini CLI extensions become Antigravity plugins through agy plugin import gemini. Skills move from .gemini/skills to .agents/skills, and Model Context Protocol (MCP) servers move to mcp_config.json. Google stated that the CLI did not have full feature parity with Gemini CLI at launch.

Google also released the Antigravity SDK as a Python research preview under the Apache 2.0 license, installed via pip install google-antigravity. The SDK includes a policy engine, hooks, MCP, skills, subagents and structured output. TypeScript and Go versions are planned. TechCrunch reported the launch of the 2.0 desktop app and the CLI at Google I/O 2026.

• Install the CLI on macOS, Linux, and Googlebook using curl -fsSL https://antigravity.google/cli/install.sh | bash per the CLI install docs.
• Install the CLI on Windows PowerShell using irm https://antigravity.google/cli/install.ps1 | iex.
• Convert Gemini CLI extensions into Antigravity plugins with agy plugin import gemini per the CLI migration guide.
• Install the Python SDK research preview with pip install google-antigravity.

Autonomous Agent Capabilities inside the Desktop Application

Antigravity 2.0 provides an autonomous agent runtime that coordinates subagents, terminal sandboxes, browser automation, and scheduled routines across multi-folder workspaces.

Google's feature deep dive and overview documentation list the features below.

Workspaces can span multiple directories simultaneously, with each folder maintaining its own permission boundaries. Live voice transcription lets you dictate to the agent instead of typing.

• Parallel subagents run concurrent tasks and inherit the primary agent's permissions.
• JSON-configured hooks trigger shell scripts before and after tool or model calls, so a script you choose runs around tool or model calls. Workspace hooks override global hooks.
• Scheduled tasks run on cron via /schedule, so a recurring job runs on the schedule you set.
• Interactive slash commands include /goal, /grill-me, /browser, and /plan (plan mode to implementation plan).
• Extensible tool support integrates custom rules, skills, plugins from the marketplace, and MCP servers, covered in our Google Antigravity skills guide.
• A dedicated browser instance includes allow and deny lists and operates with a separate Chrome profile.
• A local terminal sandbox confines command execution, alongside support for structured artifacts.

Platform Additions and Model Transitions after Launch

Following the May 2026 launch, Google released several updates to Antigravity 2.0 that introduced collaboration features, third-party editor integrations, and a new Gemini model.

On August 12, 2026, Google added custom agents. On August 20, 2026, Google released the editor extensions covered above and made Antigravity available in Gemini Enterprise.

On August 21, 2026, Google introduced Remote Control, which allows developers to drive an active machine session from any mobile or desktop web browser and receive push notifications. Teamwork preview followed on August 27, 2026, accessible to all paid subscribers via the /teamwork-preview slash command.

On October 13, 2026, Google announced Gemini 4 Argon, rolling out the model inside the 2.0 desktop application and CLI for Google AI Ultra and eligible Gemini Enterprise users. Gemini 4 Argon is not available in the Antigravity IDE. The Gemini 4 Argon guide covers the release.

According to the official Antigravity models documentation, Google will remove Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120B on November 2, 2026. Nano Banana 2 handles images. After November 2, the free plan's only listed model is Gemini 3.8 Flash, and Pro adds Claude Sonnet 5.5 and Opus 5.5 on non-trial accounts.

• Gemini 4 Argon: available exclusively in Antigravity 2.0 and CLI for Ultra and eligible Enterprise users (not in the IDE).
• Gemini 3.8 Flash: available across Free, Pro, Ultra, and Enterprise tiers.
• Gemini 3.7 Flash, 3.6 Flash, and 3.1 Pro: available exclusively to Enterprise subscribers.
• Claude Sonnet 5.5 and Claude Opus 5.5 (thinking): available on Pro (non-trial accounts), Ultra, and Enterprise.
• Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120B: scheduled for deprecation and removal on November 2, 2026.

Plan Tiers and Monthly Pricing Structure

Google Antigravity 2.0 offers a free Individual tier alongside paid plans starting at $20 per month for Google AI Pro and $100 per month for Google AI Ultra.

Google changed the plans on May 19, 2026, as detailed in Google's plan update and official pricing page. The free Individual plan carries basic weekly limits, unlimited Tab completions, and unlimited Command requests, with quotas resetting once a week.

Google AI Pro costs $20 per month and resets its quota every 5 hours until users reach an overarching weekly ceiling. Google AI Ultra costs $100 per month, providing 5 times the token rate limit of Pro with a 5-hour refresh clock. A higher Ultra tier costs $200 per month (reduced from an earlier $250 price point), delivering 20 times the rate limit of Pro.

Gemini Flash and Gemini Pro models share a single unified quota, drawn down according to application programming interface (API) pricing rates. Non-Gemini models, such as Claude variants, draw against separate fixed limits. Base plans no longer bundle AI credits. Instead, overages are handled through an AI Credit Overages toggle set to Never or Always, billed at Gemini Enterprise consumption rates.

For teams, Business plans via Google Cloud start at $30 per seat monthly for Standard and Plus, or operate as pay-as-you-go with a $0 seat fee plus consumption pricing. Eligible Gemini Enterprise Standard and Plus tiers include Antigravity with administrative budget controls, audit logging, and MCP access restrictions. Google does not publish numeric token quotas, request counts, credit-pack prices, or student discounts. The Google Antigravity pricing guide has detailed plan comparisons.

• Individual (Free): $0 per month, basic weekly rate limits, unlimited Tab completions and Command requests.
• Google AI Pro: $20 per month, 5-hour quota reset cycle, access to Claude 5.5 models on non-trial accounts.
• Google AI Ultra ($100/mo): 5x Pro rate limit, 5-hour reset cycle, access to Gemini 4 Argon.
• Google AI Ultra ($200/mo): 20x Pro rate limit, highest weekly allowance.
• Business via Google Cloud: from $30 per seat monthly, or $0 seat fee with pay-as-you-go consumption billing.
• No bring-your-own-key option exists to expand rate limits beyond your subscription tier.

Known Technical Issues and Account Restrictions

Antigravity users have reported quota lockouts, HTTP 429 errors, two security incidents and account bans since the IDE launched in November 2025.

In January 2026, Google acknowledged a bug on the Google AI developer forum where rolling 5-hour quota resets failed for Google AI Pro users, leaving accounts stuck in multi-day lockout loops.

Developers also report Hypertext Transfer Protocol (HTTP) 429 errors returning RESOURCE_EXHAUSTED and displaying 'Agent execution terminated due to error', as documented on the developer community forum. When you reach a limit, the AI Credit Overages setting decides what happens: Never stops the work, and Always continues it at Gemini Enterprise consumption pricing.

In December 2025, technology publication The Register reported that a turbo-mode command wiped a user's drive. In April 2026, cybersecurity news site CyberScoop reported a vulnerability discovered by Pillar Security where prompt injections achieved remote code execution even in strict mode, which Google fixed on February 28, 2026. The terminal sandbox and the browser allow and deny lists are the 2.0 controls for limiting what the agent can touch.

In February 2026, Google began issuing account bans against users connecting the third-party agent OpenClaw to Antigravity, as reported by VentureBeat. Do not connect OpenClaw to an Antigravity account.

Antigravity 2.0 is not suited for engineers who want to edit source code by hand in the same window where their AI assistant runs. Because 2.0 contains no code editor, users who need immediate manual code manipulation should use the Antigravity IDE or install an Antigravity extension inside Visual Studio Code or JetBrains.

Two operational shifts would change this recommendation. If Google ships the announced Agent Manager removal from the Antigravity IDE, keeping the IDE will no longer give you the IDE's Agent Manager. If Google brings Gemini 4 Argon to the IDE, Ultra and eligible Enterprise users could use Argon without leaving the IDE.

Read Google Antigravity explained for how 2.0, the IDE, the CLI and the SDK fit together. Then follow how to use Google Antigravity to set up your first workspace.

• HTTP 429 RESOURCE_EXHAUSTED errors end the agent run; the AI Credit Overages setting decides whether work continues past your limit.
• Do not route third-party orchestration wrappers like OpenClaw through Antigravity accounts to avoid service bans.
