Requires a Google API key, described as an unofficial third-party tool with no Google affiliation.

The README does not state a license.

So what is it?

Gemini Antigravity CLI is an unofficial command-line tool for interacting with Google's Gemini AI models directly from the terminal. You type a question or coding request and the tool responds using Gemini, without needing to open a browser or use Google's own interface. It supports Gemini 2.5 Pro and Flash models as well as a variant called Antigravity. The README notes this is a third-party tool with no affiliation to Google, and that using it requires a Google API key. The tool is installed via npm or by downloading a prebuilt executable from the releases page. Running the "antigravity" or "gemini" command starts an interactive session in the terminal. Slash commands like /help and /model are available inside the session for navigating features and switching models. Beyond basic chat, the README describes support for an MCP server and plugin system. MCP (Model Context Protocol) is a standard for connecting AI tools to external data sources and services. There is also mention of agentic workflows and coding assistance, meaning the tool can take multi-step actions rather than just answering single questions. The README describes it as context-aware, meaning it tracks the conversation as it progresses. The project runs on Windows, macOS, and Linux. The README is brief and does not go into detail about how the plugin system works or what specific agents are available. The tool is described as a migration-friendly alternative to Google's own Gemini CLI.
