Google Antigravity is an 'agent-first' coding tool built for Gemini 3
"One of the key components of Antigravity is how it reports on its own work. As it completes tasks, it will produce what Google calls Artifacts: task lists, plans, screenshots, and browser recordings that are intended to verify both the work it's done and what it will do. Antigravity will also report on its actions and external tool use along the way, but Google says that Artifacts are "easier for users to verify" than full lists of a models' actions and tool calls."
"Antigravity's other big change is that it offers two main usage views. The default Editor view offers a familiar Integrated Development Environment (IDE) experience, similar to rivals like Cursor and GitHub Copilot, with an agent in a side panel. The new Manager view is instead designed for controlling multiple agents at once, allowing each to work more autonomously. Google compares it to "mission control for spawning, orchestrating, and observing multiple agents across multiple workspaces in parallel.""
"Google has introduced more ways to give feedback to AI agents as they work, with the ability to leave comments on specific Artifacts for an agent to take into account without breaking up its work to do so. The company also says that agents in Antigravity will be able to "learn from past work," retaining specific snippets of code or the steps required to carry out certain tasks."
Antigravity integrates Gemini 3 Pro and third-party models to support multiple agents with direct access to the editor, terminal, and browser. It creates Artifacts—task lists, plans, screenshots, and browser recordings—to verify completed and planned work, and it reports actions and external tool use for accountability. Antigravity offers an Editor view with an IDE-like agent side panel and a Manager view for spawning, orchestrating, and observing multiple autonomous agents across workspaces. The tool accepts comments on specific Artifacts so agents can continue without interruption, and agents can retain code snippets and procedural steps from past work. Public preview is available on Windows, macOS, and Linux, free with generous rate limits and support for additional models.
