Gemini CLI is Google's open-source (Apache 2.0) AI agent for the terminal, with a 1M-token context window that can hold entire codebases, MCP servers, Google Search grounding, and shell command execution in an agentic loop. It is no longer free: on June 18, 2026 Google stopped serving Gemini CLI to free accounts and to Google AI Pro and Ultra subscribers, and replaced it for those users with Antigravity CLI. Gemini CLI itself is still maintained and now runs on a Gemini Code Assist Standard or Enterprise licence or a paid Gemini API key.
GitHub Copilot is the most widely-adopted AI coding assistant. It offers inline code suggestions, chat-based assistance, and tight integration with the GitHub ecosystem including pull requests, issues, and Actions. Available in VS Code, JetBrains, Neovim, and more.
