Antigravity CLI vs Cline: which should you start with?

Google's terminal agent versus an open-source agent that works in your editor and terminal with many AI providers.

Antigravity CLI vs Cline

Verdict

Pick Antigravity CLI if you want a terminal agent from Google that you can start on with a personal Google account. Pick Cline if you want an agent inside your editor, a stated open-source licence and the freedom to switch AI providers. With Cline you pay for the AI usage behind it.

Antigravity CLI is Google's terminal agent. Cline is an open-source coding agent for your editor (such as VS Code) and terminal, where you choose the AI model. Both read your project, edit files and run commands from plain-English requests, and both ask before they act by default.
