OpenCode FAQ
What is OpenCode?
OpenCode is an open source AI coding agent that helps you write code through your terminal, desktop app, or IDE. It supports multiple LLM providers including Claude, ChatGPT, Google, and local models. With 60,000+ GitHub stars and 650,000+ monthly developers, it is one of the most popular open source coding assistants.
Is OpenCode free?
Yes, OpenCode is completely free and open source. You can use it with your own API keys from any provider (Claude, OpenAI, etc.) at no additional cost. Alternatively, OpenCode Zen offers pay-as-you-go access to optimized models starting at 20 dollars pre-paid balance with zero markup on requests.
How does OpenCode compare to Claude Code?
Both are terminal-based AI coding assistants. Claude Code is Anthropics official CLI requiring a Claude subscription (20 dollars per month Pro). OpenCode is open source and provider-agnostic - it works with Claude, ChatGPT, or any LLM. OpenCode offers more flexibility but requires configuration, while Claude Code is more plug-and-play for Claude users.
What LLM providers does OpenCode support?
OpenCode supports virtually any LLM provider: Anthropic Claude (including Pro/Max subscriptions), OpenAI ChatGPT (Plus/Pro), Google models, and 75+ providers through Models.dev. You can also run local models. OpenCode Zen offers curated models benchmarked specifically for coding tasks.
What are the specialized agents in OpenCode?
OpenCode includes five specialized agents: Build agent (full development with all tools), Plan agent (analysis without changes), Review agent (code review with read-only access), Debug agent (investigation focused), and Docs agent (documentation with file operations). You can switch between agents based on your task.
Can I use OpenCode with VS Code or Cursor?
Yes, OpenCode has IDE extensions for VS Code and popular forks like Cursor, Windsurf, and VSCodium. You can also use the terminal interface within any IDEs integrated terminal, or the standalone desktop app available for macOS, Windows, and Linux.
How does OpenCode handle privacy?
OpenCode is designed for privacy-sensitive environments. It does not store any of your code or context data. When using OpenCode Zen, there is zero data retention for model training (with limited exceptions). Your code stays between you and your chosen LLM provider.
