AI tool · Paid
Anthropic's agentic coding tool that works in your terminal, IDE and the web: it reads your codebase, edits files, runs commands and supports skills.
AI tool · Open source
Google's open-source terminal agent that uses Gemini models to read code, edit files and run commands.
Our verdict
Claude Code is a paid agent that works across terminal, IDE and web, and is aimed at multi-step changes across a whole repository plus custom skills. Gemini CLI is an open-source terminal agent built on Gemini models, with a free tier and a large context window that suits codebase questions. Both can run commands and edit files, so the choice comes down to whether you want a paid, broader tool or a free, terminal-focused one.
Pick Claude Code if you want an agent for multi-step work across a repository, you work mainly in the terminal or an IDE, and you're willing to pay for it.
Pick Gemini CLI if you want a free, open-source terminal agent and mainly need help understanding large codebases.
