In conjunction with today’s launch of Gemini 3 Pro, Google has also unveiled Antigravity—a developer tool powered by Gemini 3 Pro and other third-party models. According to Google, Antigravity supports multiple agents and grants them direct access to the editor, terminal, and browser, embodying a “future-first agent” design philosophy.

A key feature of Antigravity is how it documents its own work. As tasks are completed, it generates what Google calls “artifacts”—including task lists, plans, screenshots, and browser recordings—intended to verify both past accomplishments and guide future actions. While Antigravity also logs its actions and usage of external tools throughout the process, Google emphasizes that these artifacts offer a more digestible and verifiable summary compared to raw model action logs and full tool-call histories.

Another significant innovation in Antigravity is its dual-view interface. The default Editor View delivers a familiar integrated development environment (IDE) experience, similar to rivals like Cursor and GitHub Copilot, featuring an agent panel on the side. The new Manager View, however, is built for orchestrating multiple agents simultaneously, enabling each to operate with greater autonomy. Google describes this as a “mission control center” for generating, coordinating, and monitoring multiple agents across parallel workspaces.

Google has also introduced enhanced feedback mechanisms that allow users to comment directly on specific artifacts while agents continue working uninterrupted. Additionally, the company notes that Antigravity’s agents can “learn from prior work,” retaining useful code snippets or sequences of steps required for recurring tasks.

Antigravity is now available in public preview for Windows, macOS, and Linux. It is free to use, with what Google describes as “generous rate limits” for Gemini 3 Pro. The tool also supports Claude Sonnet 4.5 and OpenAI’s GPT-OSS. Rate limits refresh every five hours, and Google states that only a “very small number of power users” are likely to hit these caps.
