If you like Claude Code, then you definitely need to use OpenCode.
It’s not only the official open-source alternative, it’s actually ahead of the official product.
Model freedom: Claude, GPT, Gemini, and even local models — switch freely and use whichever is strongest.
Lower costs: simple busywork automatically switches to a cheaper model (or a local model), so there’s no need to burn Sonnet or Opus the whole time.
Perfect compatibility: Claude Skills work right away; just copy and paste them into .opencode/skills.
Native multi-agent: built-in Plan/Build dual modes, and with Oh My OpenCode, it turns straight into an AI development team.
