What is Antigravity? Breaking Down Google’s New AI Agent-First Development Tool

Google Antigravity AI

The coding landscape just experienced a seismic shift. On November 18, 2025, Google unveiled Google Antigravity, an entirely new approach to software development that’s turning the traditional IDE on its head. Combined with the launch of Gemini 3, Google’s most advanced AI model to date, this release signals a fundamental reimagining of how developers build applications in the age of AI agents.

The Agent-First Revolution in Software Development

For years, developers have worked with AI coding assistants like GitHub Copilot and Cursor, where the AI sits quietly in the sidebar, offering suggestions when prompted. Antigravity flips this paradigm completely. Instead of AI being embedded within your tools, the tools are embedded within the AI agent.

Think of it as promoting your AI assistant from junior developer to project architect. Rather than asking the AI to generate a function or fix a bug, you tell it: “Build me a flight tracker application with real-time updates,” and it handles everything from planning the architecture to writing code, running tests, and verifying the final product in a browser.

What Makes Google Antigravity Different from Traditional AI Coding Tools?

1. Autonomous Multi-Surface Operations

Antigravity agents operate simultaneously across three critical environments:

  • The Code Editor: Writing and modifying files
  • The Terminal: Executing commands and running scripts
  • The Browser: Testing interfaces and verifying functionality

This direct access enables agents to complete complex, end-to-end tasks without requiring constant human intervention at every step. Agents gain direct access to essential development environments: the code editor for writing and editing files, the terminal for executing commands and running scripts, and the browser for interacting with web applications and testing interfaces. It’s like having a developer who can think, code, test, and deploy all on their own.

2. Trust Through Artifacts: Verifiable AI Development

One of the biggest challenges with autonomous AI is trust. How do you know the agent is doing what you think it’s doing? Google’s solution is elegant: Artifacts.

Instead of showing raw command outputs and endless logs, Antigravity produces easy-to-verify deliverables including task lists outlining what needs to be done, implementation plans detailing the approach, screenshots capturing the current state of applications, and browser recordings showing how the final product actually works.

These artifacts serve as checkpoints, allowing you to verify the agent’s work and provide feedback without micromanaging every action.

3. Two Modes for Different Workflows

Antigravity offers flexibility in how you work:

Editor View: An Integrated Development Environment experience akin to established tools such as Cursor and GitHub Copilot, where a single agent operates within a side panel alongside the main editing area.

Manager View: This is where things get interesting. Users control several autonomous agents concurrently across various workspaces, described as “mission control for spawning, orchestrating, and observing multiple agents across multiple workspaces in parallel”. You become the architect, directing high-level strategy while agents handle execution.

4. Asynchronous Feedback Loops for Continuous Improvement

Traditional coding assistants often complete 80% of a task, then leave you to finish the remaining 20%, sometimes taking more time than they saved. Antigravity solves this with feedback mechanisms that allow non-disruptive communication with agents, similar to Google Docs-style commenting directly on artifacts and screenshots.

Agents incorporate this feedback without needing to be stopped or restarted, creating a continuous improvement cycle that feels more like collaboration than instruction.

5. Built-In Memory and Learning Capabilities

Antigravity maintains an internal knowledge base, learning from your past projects. It remembers code snippets, architectural patterns, and the steps that successfully completed previous tasks. Over time, it becomes more aligned with your development style and project requirements.

The Power Behind the Platform: Gemini 3 Pro

Antigravity’s capabilities are powered by Google’s newly released Gemini 3 Pro model, which Google describes as their most intelligent model that helps bring any idea to life with state-of-the-art reasoning and multimodal capabilities. The numbers are impressive:

  • 54.2% on Terminal-Bench 2.0: Testing tool use ability to operate computers via terminal
  • 1487 Elo on WebDev Arena: Topping the leaderboard for web development tasks
  • 76.2% on SWE-bench Verified: A benchmark that measures coding agents

Gemini 3 Pro got first place in the Artificial Analysis Intelligence Index comprising 10 different evaluations, three points above the second-best model, OpenAI’s GPT-5.1, representing the largest gap in a long time.

Perhaps most intriguingly, Google is promoting the concept of “Vibe Coding” where natural language becomes the primary syntax, allowing users to generate code with prompts. Describe the feeling and functionality you want, and let the agent scaffold the entire application.
