Claude Code vs Gemini CLI
Two terminal coding agents compared on pricing, model access, context, workflow, and openness.
Updated June 30, 2026 · Independent comparison — Claude Code and Gemini CLI are separate products.
Claude Code
Anthropic's terminal-first coding agent
Claude Code is Anthropic's terminal-first coding agent for reading, editing, testing, and navigating codebases from the command line. It is proprietary and is available through Anthropic API usage or eligible Claude subscriptions, with advanced workflow features such as MCP, subagents, hooks, skills, plan mode, slash commands, and IDE extensions.
Gemini CLI
Google's open-source terminal coding agent
Gemini CLI is Google's Apache-2.0 open-source terminal agent for coding, shell, file, and web tasks. It uses Gemini models through supported Google access paths, with MCP, extensions, built-in tools, a ReAct-style loop, large context windows, and GEMINI.md project instructions.
Bottom line
Two terminal coding agents compared on pricing, model access, context, workflow, and openness. Choose Claude Code if you want Anthropic's Claude models as the primary coding brain; choose Gemini CLI if you want an Apache-2.0 open-source CLI client you can inspect and extend.
