Claude Code and OpenCode are leading terminal-based AI agents. Claude Code offers a polished, stable experience optimized for Anthropic’s models (Opus, Sonnet) via a subsidized subscription,. While it recently added Ollama support, it excels within its native ecosystem,.

In contrast, OpenCode is open-source, offering "bring your own key" flexibility for diverse models (including OpenAI),. However, accessing Anthropic models in OpenCode is significantly costlier via API since Anthropic restricted third-party access to their subsidized subscription plans,.

Both tools share core agentic features like planning modes, MCP support, and skills, though configuration files differ slightly,. Reviewers often favor Claude Code for superior flow and stability ("the Apple of CLIs"), while OpenCode is preferred for model agnostic flexibility and transparency,,.
