Google's open-source terminal agent that uses Gemini models to read code, edit files and run commands.
Our verdict
Cline is a VS Code extension that lets you plug in your own AI model and works step by step, asking your approval before it edits files or runs commands. Gemini CLI is a terminal agent from Google that runs on Gemini models and offers generous free usage, with a large context window for questions about big codebases. Both are open source and aimed at coding, so the choice mostly comes down to whether you want to work inside VS Code with a model of your choice or in the terminal with Gemini.
Pick Cline if you work in VS Code (or JetBrains) and want to choose your own model while approving each action the agent takes.
Pick Gemini CLI if you prefer working in the terminal, want a free option with a Google account, and need to ask questions across a large codebase.
