Our Review

OpenCode is an open-source AI coding agent built for the terminal. It supports 75+ LLM providers, including Claude, GPT, Gemini, and local models, with optional GitHub Copilot and ChatGPT Plus logins. A privacy-first design means no code or context is stored; data is sent only to your configured provider.

Strengths: LSP integration loads language servers automatically, so you get proper language support without manual setup. Multi-session agents let you run several agents in parallel. The opencode run command handles single-task execution, and opencode serve provides a headless API for automation. MCP management supports custom tools. The tool is free; you pay only for model API usage.

Tradeoffs: Terminal-first means no GUI; you need to be comfortable with CLI workflows. Quality and speed depend on the model you choose. There is no built-in SSO or enterprise billing.

Best for: Developers who prefer terminal workflows, want maximum provider flexibility, or need a privacy-first agent that does not store code or context.

Final verdict: OpenCode is a strong open-source option for terminal-based AI coding with broad model support. It competes with Aider and Claude Code; choose OpenCode if you value multi-session agents, LSP integration, or the headless API. See our AI CLI tools overview for more context.
