Opencode vs Claude Code
Claude Code is the latest CLI programming tool launched by Anthropic, and Opencode is also a terminal-centric IDE. What are the differences?
Core Form Differences
| Feature | Claude Code | Opencode |
|---|---|---|
| Form | Pure CLI Tool (Command Line Interface) | Terminal-First IDE (TUI + GUI) |
| Dependency | Strongly dependent on Claude models | Model Agnostic, supports GPT, Claude, DeepSeek, etc. |
| Workflow | Q&A style, based on REPL | Plan -> Build dual modes, more suitable for complex engineering |
| File Editing | Auto-edit, user passively accepts | Interactive Editing, supports Diff preview and manual fine-tuning |
Why Choose Opencode?
1. Model Freedom
Claude Code is bound to Anthropic's ecosystem. Opencode allows you to switch freely. You can use GPT-4o for planning, DeepSeek Coder for coding, and Haiku for summarizing.
2. Project Awareness
Opencode's AGENTS.md mechanism allows it to persistently understand project specifications, rather than just relying on the recent Context Window.
3. Local First
Opencode supports connecting to Ollama, which means you can work in offline environments or where privacy requirements are extremely high, whereas Claude Code requires an internet connection.
