Is Google Antigravity free?

Yes, Google Antigravity offers a 'Free for Developers (Public Preview)' tier with generous weekly API rate limits. For higher usage and advanced features, Google AI Pro and Google AI Ultra/Workspace AI Ultra for Business plans are available, which are variable and utilize AI credits based on Vertex API pricing for token consumption.

What are the main features of Google Antigravity?

Key features of Google Antigravity include tab autocompletion, natural language code commands, synchronized agentic control, user feedback integration, and the ability to manage multiple AI agents in parallel. It supports autonomous planning, execution, and verification of complex engineering tasks across the editor, terminal, and an integrated browser, generating verifiable deliverables like task lists, screenshots, and browser recordings.

How does Google Antigravity compare to alternatives?

Google Antigravity differentiates itself as an 'agentic development platform' with a focus on autonomous AI agents, unlike traditional code assistants. It competes with platforms like Gemini Code Assist (another Google offering with broader IDE integration), and open-source frameworks such as CrewAI and Microsoft AutoGen, which provide more granular control for building multi-agent systems. Kiro also offers autonomous agents for development tasks, positioning it as a direct competitor in the autonomous agent space.

overview

What is Google Antigravity?

Google Antigravity is an AI-powered integrated development environment (IDE) tool developed by Google that enables software developers to orchestrate autonomous AI agents to plan, execute, and verify complex engineering tasks. It operates on an 'agent-first' paradigm, primarily powered by Google's Gemini 3.1 Pro and Gemini 3 Flash models. Announced on November 18, 2025, alongside the release of Gemini 3, Google Antigravity allows developers to delegate complex coding tasks to AI agents. These agents autonomously plan, execute, and verify tasks across the editor, terminal, and an integrated browser. Key functionalities include planning, writing, testing, and verifying code, debugging, generating documentation by analyzing project files and functions, and optimizing code for performance. The platform is designed to handle multi-tool software tasks, enabling agents to manage end-to-end workflows such as writing new features, launching applications via the terminal, and testing them in a browser. It also supports routine tasks like codebase research and bug fixes.

pricing

Google Antigravity Pricing & Plans

Google Antigravity operates on a freemium model, offering a free public preview tier with varying rate limits, and paid tiers that utilize AI credits for expanded usage. Pricing for paid tiers is dynamically correlated with the amount of work performed by the agent and is based on Vertex AI API pricing for token consumption.

Free for Developers (Public Preview): Free, includes generous weekly API rate limits.
Google AI Pro plans: Variable (AI credits), offering a high, generous API quota refreshed every five hours until a weekly limit is reached. Additional usage beyond the baseline quota is covered by purchasing AI credits at Vertex API pricing.
Google AI Ultra or Google Workspace AI Ultra for Business plans: Variable (AI credits), providing the highest, most generous API quota refreshed every five hours, with no weekly API rate limit. Additional usage beyond the baseline quota is covered by purchasing AI credits at Vertex API pricing.
API Usage (Gemini 3 Pro): Internal references indicate token-pricing at approximately $0.002 per 1k input tokens ($2 per million input tokens) and $0.012 per 1k output tokens ($12 per million output tokens) when AI credits are consumed at Vertex API pricing.

Similar Tools

Google Antigravity vs Competitors

Google Antigravity is positioned as an 'agentic development platform' focusing on autonomous AI agents for orchestrating and verifying complex software tasks. It differentiates itself from traditional AI code assistants by emphasizing agent autonomy and parallel workflows.

Gemini Code Assist↗

It integrates Google's Gemini AI directly into IDEs and the terminal for comprehensive software development lifecycle support, including multi-file edits and full project context.

Similar to Google Antigravity, Gemini Code Assist provides an agent-first approach across the editor and terminal, offering a freemium model for individuals and enterprise options for teams.

CrewAIOn Stork Compare

CrewAI is an open-source Python framework specifically designed for orchestrating collaborative, role-playing autonomous AI agents into teams to complete complex tasks.

Unlike Google Antigravity, which is presented as a comprehensive platform, CrewAI is a framework, offering developers more granular control and flexibility in building their agentic systems, with an open-source (free to use) model.

Microsoft AutoGenOn Stork Compare

It is an open-source framework from Microsoft for building multi-agent AI systems that can converse and collaborate to solve tasks, including software engineering workflows.

Similar to CrewAI, AutoGen is an open-source framework for multi-agent orchestration, providing a foundational layer for developers to build agentic solutions, whereas Google Antigravity is described as a more integrated, agent-first development platform.

Kiro↗

Kiro focuses on autonomous agents that work independently on development tasks, planning, coding, testing, and creating pull requests across multiple repositories.

Kiro directly competes by offering an autonomous agent that handles complex engineering tasks across repositories, similar to Antigravity's agent capabilities, but appears to be a distinct product with a preview/paid model rather than a broad platform.
