Google Antigravity

Google Antigravity is Google's agentic development platform, published as a product family rather than a single app: a desktop application (Antigravity 2.0, with a separate standalone Antigravity IDE), a command-line agent, a Python SDK for constructing and orchestrating agents, and extensions that carry the same agent into VS Code, Visual Studio, JetBrains IDEs, Zed and Xcode. The download page states macOS 12 or later on Apple Silicon or Intel, Windows 10 or later on x64 or ARM64, and Linux on x64 or ARM64, and marks the product Generally Available rather than in preview.

The pricing page lists an Individual plan at $0/month — the vendor's wording is that you can experience Antigravity without a subscription plan — with access to Gemini 3.8, 3.7 and 3.6 Flash, Gemini 3.1 Pro, Claude Sonnet and Opus 4.6, and gpt-oss-120b, plus unlimited tab completions and unlimited command requests under basic weekly rate limits. Google AI Pro and Google AI Ultra raise those limits and add a flexible AI credit pool, and an organisation plan is sold through Google Cloud with consumption-based API pricing. The same agent harness is also reachable as a managed service in the Gemini API: the changelog records antigravity-preview-09-2026 as published on 17 September 2026, replacing the deprecated antigravity-preview-05-2026, and the documentation describes it as a stateful agent that plans, executes code, manages files and browses the web inside an isolated Linux sandbox. Model lists, limits and plan names in this line move quickly and were read from Google's own pages on 2026-09-20. Nothing was installed or run for this listing, so every capability statement above is Google's account of its product, not an assessment made here.
