OpenCode

Why OpenCode over the others

vs Codex & Claude Code — both lock you to one vendor (OpenAI or Anthropic). OpenCode is provider-agnostic: 75+ LLM providers, including Claude, GPT, Gemini, and local models — switch models per task without changing tools. Free models are included, so you can start with zero subscriptions.

vs Cursor — Cursor is an editor you switch into; OpenCode is an agent that runs in your terminal and the editor you already use. Cursor is closed-source and subscription-gated; OpenCode is open-source and free.

The one thing only OpenCode has — bring both your GitHub Copilot and your ChatGPT Plus/Pro subscriptions into one tool. Neither Codex nor Claude Code accepts a Copilot login.

When it's not the right pick

• You want a polished all-in-one editor with inline AI — Cursor fits better.
• You're all-in on OpenAI and want tight cloud-run integration — Codex's chatgpt.com/codex is more seamless.
• You prefer Anthropic's reasoning and don't need other models — Claude Code is simpler.

Quick start

Install it, run opencode, pick a model (free ones included) or sign in with GitHub Copilot / ChatGPT — no API key required to start. Works on macOS, Linux, and Windows.

Privacy-first: OpenCode stores none of your code or context, so it fits privacy-sensitive environments where vendor-hosted agents can't.
