About Google Antigravity
Google Antigravity is an agent-first IDE built around Gemini 3 that shifts developers from writing code to managing autonomous agents that plan, execute, and self-verify multi-step tasks. The product is in free public preview and competes directly with Cursor and Claude Code for the AI-native editor crown.
What is Google Antigravity?
Overview
Google Antigravity launched in late 2025 as Google's first serious entry into the AI-native code editor space, arriving alongside Gemini 3 Pro. Unlike Cursor, which retrofits AI features onto a VS Code fork, Antigravity is built from the ground up around the idea that the developer is a manager of agents rather than the person typing every line of code. The IDE ships with a familiar editor surface but layers a separate Manager view on top, where you can spin up multiple agents working in parallel across different tasks and branches.
The product is currently in free public preview for macOS, Windows, and Linux, with no credit limits or paywalls during the preview window. That makes it one of the cheapest ways to access Gemini 3 Pro's full coding capabilities while Google figures out long-term pricing.
Core Features
Antigravity's headline feature is Artifacts and Verifications. Every agent run produces structured artifacts such as task lists, implementation plans, screenshots, browser traces, and test results. The agent then self-verifies its own work by running tests, taking screenshots of UI changes, and comparing them against the spec before declaring the task done. This loop dramatically reduces the babysitting required compared to first-generation agent tools.
The Manager surface is where Antigravity diverges from Cursor and Windsurf. Instead of a chat panel, you get a control center showing all active agents, their current step, the files they have touched, and their verification status. You can pause, redirect, or fork an agent at any point.
Antigravity ships with deep browser control built in. Agents can spin up a Chromium instance, navigate to your local dev server, click through user flows, and capture screenshots as evidence that the feature works. This is closer to what Claude Code with Computer Use can do, but it is native to the IDE instead of a separate tool.
Model and Performance
Gemini 3 Pro powers the agent loop, and it is fast. Google has tuned the editor for low-latency tool calls, and the agent feels noticeably more decisive than earlier Gemini-powered tools like Jules. The model also handles long-horizon tasks better than Gemini 2.5, which was Antigravity's biggest weakness before the 3.0 launch.
Pricing Analysis
During the public preview, Antigravity is completely free with generous Gemini 3 Pro quotas. Google has not announced post-preview pricing, but the company has signaled that a paid tier will likely launch in 2026 with workspace and enterprise features. Compared to Cursor's $20 per month and Claude Code's $20 minimum, the free preview is a major incentive to try the tool now.
Who Should Use Antigravity
Antigravity is built for developers who already trust agents to do meaningful work and want a manager-style interface rather than a chat panel. It is the strongest choice for full-stack engineers building features end to end, frontend developers who benefit from the browser verification loop, and teams already standardized on Google Cloud, Gemini, or Firebase.
It is less suited for developers who prefer to drive every keystroke themselves or work primarily in languages and frameworks where Gemini 3 is not yet best-in-class. Heavy Python and JavaScript users will get the most mileage today.
Pros
- Free public preview with full Gemini 3 Pro access and no usage caps
- Manager view lets you orchestrate multiple parallel agents from one control surface
- Artifacts and Verifications produce auditable evidence (screenshots, tests) that the task is actually done
- Native browser control means agents can verify UI changes end to end without external tools
- Backed by Google with first-party Gemini integration, ensuring tight model-editor coupling
Cons
- Brand new product - the editor lacks the mature extension ecosystem of VS Code-based tools
- Long-term pricing is unknown, making it risky for teams to standardize on today
- Gemini 3 Pro, while strong, is not always the best model for every language and may trail Claude on certain refactors
How to Use Google Antigravity
- 1Download and Sign In
Install Antigravity from antigravity.google and sign in with your Google account to activate the free preview.
- 2Open Your Project
Open a project folder and let Antigravity index the codebase. The Manager view appears alongside the standard editor.
- 3Spin Up an Agent
Describe a task in plain English in the Manager view. Antigravity generates a plan, asks for clarification if needed, then begins executing.
- 4Review Artifacts and Verifications
As the agent works, it produces artifacts like screenshots, test runs, and a step-by-step trace. Review these before accepting changes.
- 5Run Agents in Parallel
Open additional agent sessions for independent tasks. The Manager surface shows all active agents and their status.
- 6Approve or Iterate
If the result looks correct, commit the changes. Otherwise, send the agent back with feedback - the trace makes it easy to pinpoint where it went wrong.
