Use Claude Code CLI with OpenCode Go or Zen

Claude Code CLI is great, but it only talks to Anthropic’s API. If you are on OpenCode Go ($5/mo) or OpenCode Zen (pay-as-you-go), you cannot plug Claude Code in directly. The APIs do not match.

I put together a small open-source setup kit that wires it up:

Claude Code CLI  →  routatic-proxy (localhost)  →  OpenCode Go or Zen

What the kit does

• One script: install proxy + Claude CLI + configs
• Choose Go or Zen at setup
• Auto or guided install (Windows / Mac / Linux)
• No Anthropic API key needed

Quick setup

Windows (PowerShell)

git clone https://github.com/abdullahmiraz/OPENCODE_CLAUDE_CLI.git
cd OPENCODE_CLAUDE_CLI
.\scripts\setup.ps1

macOS / Linux / Git Bash

git clone https://github.com/abdullahmiraz/OPENCODE_CLAUDE_CLI.git
cd OPENCODE_CLAUDE_CLI
bash scripts/setup.sh

Then run `claude`. To verify the install without making API calls:

.\scripts\check.ps1    # Windows
bash scripts/check.sh  # Bash

Why a proxy

Claude Code speaks the Anthropic API shape. OpenCode Go/Zen does not. routatic-proxy sits in the middle and translates requests, so you keep the Claude Code workflow while billing through OpenCode.

Credit to the routatic-proxy project for doing the hard translation work. The kit is mostly packaging: install, config templates, and a path that does not assume you already know every moving part.

If you have been trying to run Claude Code on OpenCode, this might save you an afternoon.
