In-Depth Comparison

Gemini CLI Overview

Gemini CLI is Google's open-source AI agent for the terminal. Its standout traits are a 1M-token context window that can hold entire codebases and a free tier generous enough for real daily work with just a personal Google account. It supports MCP servers, Google Search grounding, and shell command execution in an agentic loop.

Roo Code Overview

Roo Code began as a fork of Cline and grew into its own power-user favourite. Its signature feature is modes: switchable personas like Architect (plan), Code (build), and Debug (fix), plus fully custom modes with their own prompts and tool permissions. It supports auto-approval settings for hands-off runs, MCP servers, and any OpenAI-compatible provider. The trade-off for all that configurability is a steeper setup than Cline — and, like every BYO-key agent, your API bill scales with how hard you run it.
