Google Antigravity is Google's developer platform for building and running AI agents. It gives you a command-line interface (CLI), Python SDK, and a full IDE to run autonomous coding agents, manage multiple agents in parallel, and automate software tasks. The 2.0 release added Projects for grouping agent conversations, multi-workspace support, and scheduled message automation. It's free for individual developers; enterprise tiers are available for teams.

Strengths

Built and backed by Google — integrates with Gemini 3.5 Flash and the broader Google Cloud ecosystem
Covers the full agent development workflow: interactive CLI, Python SDK for scripting, and full IDE
Free for developers with no sign-up friction, lowering the barrier to try it

Weaknesses

Google product history means risk of deprecation — developers may hesitate to build workflows on it
Enterprise pricing not disclosed on the page — hard to budget for team use
Competes directly with Claude Code, GitHub Copilot, and Cursor in an already crowded space

Key features

CLI-first interface to run autonomous coding agents, execute shell commands, and manage background subagents from your terminal
Antigravity 2.0 app lets you run multiple local agents in parallel, grouped into Projects across workspaces
Python SDK for prototyping custom agents with minimal code — iterate on agentic apps and run evaluations
Full IDE with agent manager, artifacts, and deep codebase understanding for production-ready builds
Free for individual developers; enterprise tier available for team-wide deployment

AI features

Autonomous coding agents powered by Gemini, browser-in-the-loop agents for UX automation, multi-agent orchestration, background subagents, and AI-generated code artifacts with verification tests.

STOA verdict

Google Antigravity is a serious developer tool with a full stack of interfaces for agentic coding — CLI, SDK, IDE, and multi-agent management. It's free to start and Gemini-powered, which makes it worth trying. The main risk is Google's track record of killing developer products, so you'll want to avoid deep lock-in before the product proves long-term staying power.
