Google's agent-first development platform combining an AI IDE with multi-agent orchestration
Google Antigravity is an agentic development platform announced on the Google Developers Blog (November 2025). It pairs a familiar AI-assisted editor with a Manager Surface where developers spawn and observe agents working asynchronously across editor, terminal, and browser. Agents produce Artifacts—such as task lists, implementation plans, screenshots, and browser recordings—for review instead of relying only on raw tool logs. Public preview is offered at no cost for individuals on macOS, Windows, and Linux, with model choice including Gemini 3 Pro plus third-party models such as Claude Sonnet 4.5 and OpenAI GPT-OSS as described by Google.
Use cases
- Delegate end-to-end feature work where an agent edits code, runs the terminal, and verifies in the browser
- Run long-running bug reproduction and fix pipelines while monitoring progress asynchronously
- Iterate on UI changes with screenshot-backed updates for faster visual review
- Coordinate multiple agents on parallel maintenance tasks without blocking the main editor session
Key features
- Editor View: AI-powered IDE with tab completions and inline commands for hands-on coding
- Manager Surface: orchestrate multiple agents asynchronously across workspaces
- Cross-surface agents: planning and execution spanning editor, terminal, and browser
- Artifacts: review deliverables such as plans, screenshots, and recordings instead of only tool traces
- Knowledge retention: agents can save snippets and context for reuse on later tasks
- Model optionality: Gemini plus supported third-party models (per Google's announcement)
Who Is It For?
- Software engineers adopting agent-first workflows
- Teams evaluating Google's Gemini-backed tooling alongside other model providers
- Developers who want structured verification artifacts from autonomous agents
Frequently Asked Questions
- Where did Google announce Antigravity?
- Google introduced Antigravity on the Google Developers Blog under "Build with Google Antigravity, our new agentic development platform" (November 2025), with downloads referenced from antigravity.google.
- Is Antigravity only Gemini?
- Google describes model optionality with generous Gemini rate limits while also listing support for Anthropic Claude Sonnet 4.5 and OpenAI GPT-OSS in the launch post.
- What are Artifacts?
- Artifacts are tangible outputs agents attach for human review—such as plans, screenshots, or recordings—so you validate outcomes without parsing raw tool-call streams.
