Google Antigravity is Google's agentic development platform — an editor, terminal, and browser combined into one workspace where you spawn, orchestrate, and observe AI coding agents rather than just chatting with one in a sidebar, built by Google and launched in public preview on November 20, 2025.
Who builds it
Antigravity is a Google product, introduced alongside the Gemini 3 model family. It ships as a downloadable desktop application for macOS, Windows, and Linux, and in 2026 expanded from a single IDE into a family of surfaces — the IDE, an "Antigravity 2.0" desktop app for higher-level task delegation, a CLI, and an SDK — that share one underlying agent harness.
Core features
- Editor View: a familiar AI-powered code editor with tab completions and inline commands for direct, hands-on coding.
- Manager Surface: a dedicated interface for spawning multiple agents at once and letting them work asynchronously across different workspaces, instead of one blocking chat thread.
- Artifacts: agents produce verifiable deliverables — task lists, implementation plans, screenshots, browser recordings — so you can check what an agent actually did instead of just reading a log.
- Browser control: agents can navigate the web, fill forms, and validate end-to-end flows without leaving the IDE.
- Persistent knowledge base: agents retain context across sessions so future tasks can build on prior work.
- Model choice: access to Gemini 3 Pro and Flash, Anthropic's Claude Sonnet and Opus, and OpenAI's gpt-oss-120b from within the same platform.
Pricing
- Individual (Free): $0/month — access to the supported model lineup, unlimited tab completions and command requests, and basic weekly rate limits; Google has described this as available "at no cost for individuals" during public preview.
- Google AI Pro tier: everything in the free plan plus more generous rate limits and a flexible AI credit pool; Antigravity's own pricing page does not list a standalone dollar price for this tier, since it is unlocked through a separate Google AI Pro subscription.
- Google AI Ultra tier: everything in Pro plus higher access to the latest Gemini models and further-expanded rate limits, again unlocked via a Google AI Ultra subscription rather than an Antigravity-specific price.
- Organization plan: available through Google Cloud under the Gemini Enterprise Agent Platform, billed with consumption-based API pricing rather than a flat seat fee.
Because the paid tiers ride on top of Google's general-purpose AI subscriptions (which also unlock Gemini app features outside of coding), check Google's current subscription pricing before budgeting, as the underlying consumer plan prices are set independently of Antigravity.
Who it's for
Developers and teams who want to run several coding agents in parallel on real, verifiable tasks — refactors, test generation, browser-based QA — rather than supervising one assistant turn by turn. The free Individual tier is enough to evaluate the workflow solo; the Google AI Pro/Ultra tiers suit developers who already lean on Gemini day to day and want higher throughput, while the Organization plan targets companies standardizing agentic development on Google Cloud.
