Antigravity is more than a Gemini CLI wrapper
Google Antigravity should be treated as more than a Gemini CLI wrapper. It is Google's agent-first development platform for building, working, and automating with software agents, and the product spans IDE, CLI, SDK, agent manager, artifacts, verification tests, and Google Cloud organization access. Pricing has a free individual entry point plus Pro, Ultra, and Google Cloud organization paths. That makes it a direct comparison target for Cursor, Kiro, and Claude Code, not just a terminal tool. The caveat is churn: Antigravity's limits and product surfaces have been changing quickly, so comparison pages need short refresh windows.
Gemini CLI is the open terminal on-ramp
Gemini CLI is the most straightforwardly free option for terminal and agent work in Google's stack: it is open source and free to start. It runs coding tasks from the command line using built-in tools and MCP servers, and it also powers Gemini Code Assist's agent mode in VS Code. Because it is open source, it is the lowest-barrier entry point into agentic coding — no paid plan required to try a real terminal agent, though heavier use can move to Code Assist quotas or a Gemini API key. It is the right pick when you want a lightweight, scriptable agent rather than a full hosted platform.
Decide by platform depth versus lightweight control
The practical decision is platform depth versus lightweight control. Antigravity is the pick when you want the full agentic development experience — IDE, agent manager, verified artifacts, and organization access through Google Cloud — and are comfortable with a hosted platform whose limits still shift. Gemini CLI is the pick when you want a free, open, scriptable terminal agent you can drop into existing workflows and CI. Many teams will start with Gemini CLI to evaluate the model and workflow for free, then move to Antigravity when they need the broader platform and verification story.
