Google Antigravity

Google Antigravity is Google's agentic development platform, launched alongside Gemini 3 in November 2025. It pairs an agent-first IDE with a Manager surface — a mission-control view where you spawn, orchestrate, and observe multiple agents working asynchronously across different workspaces. Agents don't just edit code: they act across the editor, the terminal, and a browser, and report back with Artifacts — task lists, implementation plans, screenshots, and browser recordings you can verify instead of reading raw logs.

At I/O 2026 (May 19, 2026), Google expanded it from an IDE into a product family — Antigravity 2.0 added a standalone desktop app, the Antigravity CLI for terminal-first work, and an SDK for custom agent behaviors. It is also the designated successor to Gemini CLI: as of June 18, 2026, Gemini CLI's free, Pro, and Ultra service stopped, and Google points those users to Antigravity CLI.

Highlights

• Manager surface — run several agents in parallel on different tasks and supervise them from one board, rather than babysitting a single chat.
• Browser-using agents — agents can drive a browser to verify the UI they just built, attaching screenshots and recordings as evidence.
• Artifacts over logs — plans, task lists, and recordings designed for human verification of agent work.
• Gemini models, plus others — launched with Gemini 3 Pro; as of September 2026 the agent models include Gemini 3.8, 3.7, and 3.6 Flash, Gemini 3.1 Pro, Claude Sonnet and Opus 4.6, and gpt-oss-120b, and the agent harness is co-optimized with newer Gemini releases.
• A whole product family — IDE, desktop app, terminal CLI sharing the same Core Agent Engine, and a Python SDK (Apache-2.0).

In an AI-assisted workflow

The IDE and desktop app install from the site; the CLI is one line:

# Antigravity CLI (terminal surface)
curl -fsSL https://antigravity.google/cli/install.sh | bash
 
# IDE / desktop app: download from https://antigravity.google/download

Coming from Gemini CLI, the CLI keeps the concepts you've built around — agent skills, hooks, subagents, and extensions (as plugins) — and can export terminal sessions to the Antigravity 2.0 desktop app, with settings synced between the two.

Good to know

Antigravity runs on macOS, Windows, and Linux and is proprietary — free for individuals on a generally available plan, with paid Google AI subscriptions adding higher usage limits. The closed source is a real change from Gemini CLI's Apache-2.0 openness and has drawn criticism from contributors; weigh it if open tooling matters to your team (OpenCode and Codex CLI are the open terminal-agent alternatives). Expect pricing, limits, and the model lineup to keep shifting.
