Antigravity IDE

Antigravity IDE is Google's standalone agentic development environment, integrating an editor, AI-assisted completion, agent conversations, terminal work and browser-assisted development. It is intended for developers who want agents to plan and implement changes while keeping code and structured deliverables visible for review.

Features

• Edit source files in a full development workspace with AI Tab completion.
• Direct agents from the editor's side panel and provide project context.
• Run asynchronous local agents across workspaces and codebases.
• Review structured artifacts such as plans, walkthroughs and code diffs.
• Configure supported rules, skills, workflows and MCP integrations.
• Use supported terminal and browser workflows to verify development work.

This package is Antigravity IDE, not the separate Antigravity 2.0 application, terminal CLI, SDK or IDE extensions. Their version numbers and release notes are independent. Google's current IDE overview explicitly states that Antigravity IDE is not supported for enterprise customers and directs enterprise configurations to Antigravity 2.0 or CLI; do not infer enterprise entitlement from general Antigravity service documentation.

Installation and requirements

Install the official Antigravity IDE DMG or use brew install --cask antigravity-ide, then place Antigravity IDE.app in Applications and complete the documented sign-in and setup. Choose the native Apple Silicon or Intel 64-bit download matching your Mac. The official getting-started IDE section specifies macOS 12 Monterey as a minimum and macOS versions receiving Apple security updates, typically the current and two previous releases. Its statement that x86 is unsupported means 32-bit x86; official Intel x64 and Apple Silicon downloads remain available. A minimum version does not promise continued support for an older operating system after its security updates stop.

Windows 10 64-bit and Linux with glibc 2.28 and glibcxx 3.4.25 or later have separate distributions. The Mac cask's dependency fields are empty; this does not mean every programming language or project build tool is included. Install the compilers, runtimes, package managers, Git tooling and external services required by your actual project. Browser-assisted workflows require the supported browser setup and may request a separate extension or profile; a browser agent is not a prerequisite for editing a source file.

Agent permissions and data

Agents can read and edit selected workspace files and run permitted terminal tools. Review the project trust and execution settings before granting autonomous access. Strict permission modes and review controls help limit operations; they do not make untrusted code, dependencies, MCP servers or prompts harmless. Terminal commands can modify files, access networks or invoke external services with your account's privileges. Use version control, inspect diffs and keep backups before accepting significant edits.

Browser workflows can inspect pages and interact with their contents. Use a separate profile and restrict access to the sites needed for the task, particularly around authenticated accounts. MCP integrations have their own credentials and data-access scopes. The official IDE changelog documents sensitive-path confirmations in strict mode; these controls are product behavior, not a claim that every possible private path is protected automatically.

Local editing and local agent tools do not imply an offline local model. AI requests and relevant context can be processed by Google's service. Review the applicable Google terms and privacy policy and the project's rules before sending sensitive code or data. Generated code and plans can be wrong or insecure; review them and run appropriate project checks before publication or deployment.

Account, plans and license

Google account sign-in and eligible service access are required for the documented AI experience. Individual access is governed by Google terms. Current service plans include baseline quotas without a Google AI Pro or Ultra subscription; paid Pro and Ultra plans provide higher quotas and other entitlements. Usage is limited and capacity-dependent, not unlimited free agent execution. Paid plans can use purchased AI credits for overage usage when enabled; check the account's current plan, model availability and overage setting.

The current plans documentation does not support bring-your-own-key or custom endpoints for additional rate limits. Do not borrow a CLI or SDK local-model capability and claim that this IDE supplies unrestricted offline model use. Antigravity IDE is proprietary software distributed under Google's applicable terms; no public-source license for the complete IDE is supplied by the reviewed product documentation. Extensions and project dependencies have separate licenses.

The official 2.5.5 Apple Silicon DMG is 212,175,820 bytes according to HTTP HEAD metadata. Installed files, language dependencies, repositories and agent artifacts require additional disk space.
