Google launched yet another coding agent platform Tuesday, this time focused on developer teams collaborating to create agents that can execute complex tasks automatically, in a way that moves agents from being remotely controlled to actually independent.
The platform, called Antigravity, is powered by Gemini 3 and is now available in public preview with “generous rate limits on Gemini 3 Pro usage,” Google writes in a blog post accompanying the announcement.
Antigravity is an agentic coding platform that aims to evolve the IDE toward an agent-first future with browser control capabilities, asynchronous interaction patterns, and an agent-first product design.
Enterprises that are already bogged down by a growing volume of code to review, thanks in large part to the rise of AI code generation, are demanding more from asynchronous coding agents. They need asynchronous coding agents to help developers review coding projects, assess the elements, and perform tasks autonomously.
For the public preview, Antigravity users can build agents using Gemini 3, Anthropic’s Sonnet 4.5 models, and OpenAI’s open-source gpt-oss. It will be compatible with developer environments running on major operating systems such as macOS, Linux and Windows.
“We want Antigravity to be the home base for software development in the era of agents,” Google writes in the blog. “Our vision is to ultimately enable anyone with an idea to experience liftoff and build that idea into reality.”
Google said it built Antigravity with four key tenets — trust, autonomy, feedback, and self-improvement — which it says sets it apart from other coding platforms because it focuses on a more collaborative development environment.
Key tenets of development
Enterprises today are either completely transparent about what's happening under the hood, or they don't show their work and simply split out code.
The Antigravity team doesn't think either of these two extremes build trust. "Antigravity provides context on agentic work at a more natural task-level abstraction, with the necessary and sufficient set of artifacts and verification results, for the user to gain that trust. There is a concerted emphasis for the agent to thoroughly think through verification of its work, not just the work itself," according to Google.
As for autonomy, Antigravity’s main interface, Editor View, mimics an IDE experience, standardizing what an agent might encounter while accomplishing its tasks. The agent is embedded in this interface so it can navigate it.
However, Google plans to add “an agent-first Manager surface” that flips that idea around, meaning the interface is embedded into the agent.
The Antigravity team built user feedback into “across every surface or artifact,” which will be automatically incorporated into agent execution. This would allow work to continue without requiring humans to stop the work to redirect the agent.
With the human developer iterating with the agent, "self-improvement" becomes very essential. Its agent can tap a knowledge base to learn from past work or contribute new learnings.
Google’s many coding agents
Antigravity is not Google’s only coding platform; it’s not even its only coding agent with an IDE integration or asynchronous capabilities. It joins a long line of Google platforms aimed at helping developers work more efficiently. The coding assistant Jules is now integrated into IDEs, can be invoked via the CLI, and can also run asynchronously. Gemini CLI also works similarly. And there's Gemini Code Assist, which first launched last year.
However, Antigravity will most likely have to compete more with coding agent platforms like Codex from OpenAI, Claude Code from Anthropic, and Cursor.
Some people on X commented that Antigravity looks similar to Windsurf, which would make sense: Google hired the Windsurf team — including CEO Varun Mohan — in July and licensed the tech for $2.4 billion. Varun Mohan tweeted that this came from his team:
So far, early Antigravity users have had mixed experiences, with many pointing to errors and slow generation.
