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.
OpenCode is an open-source terminal AI coding agent with a beautiful TUI (text user interface). It supports multiple LLM providers, has LSP integration for intelligent code understanding, and offers session management for long-running tasks. Designed for developers who live in the terminal.
