routatic-proxy (prev OC-GO-CC)

A Go CLI proxy that lets you use your OpenCode Go or OpenCode Zen subscription with Claude Code.

routatic-proxy sits between Claude Code and OpenCode, intercepting Anthropic API requests, transforming them to the appropriate format (OpenAI, Responses, or Gemini), and forwarding them to OpenCode's endpoints. Claude Code thinks it's talking to Anthropic — but your requests go to affordable open models instead.

oc-go-cc remains available as a compatibility alias, and existing OC_GO_CC_* environment variables and ~/.config/oc-go-cc/config.json files are still recognized.

Why?

OpenCode Go gives you access to powerful open coding models for $5/month (then $10/month). OpenCode Zen provides curated, tested models with pay-as-you-go pricing. This proxy makes both work seamlessly with Claude Code's interface — no patches, no forks, just set two environment variables and go.

Features

• Transparent Proxy — Claude Code sends Anthropic-format requests, proxy transforms to OpenAI/Responses/Gemini format and back
• Dual Provider Support — Route models through OpenCode Go or OpenCode Zen based on your needs
• Model Routing — Automatically routes to different models based on context (default, thinking, long context, background)
• Fallback Chains — If a model fails, automatically tries the next one in your configured chain
• Circuit Breaker — Tracks model health and skips failing models to avoid latency spikes
• Real-time Streaming — Full SSE streaming with live format transformation
• Tool Calling — Proper Anthropic tool_use/tool_result <-> OpenAI/Gemini function calling translation
• Token Counting — Uses tiktoken (cl100k_base) for accurate token counting and context threshold detection
• JSON Configuration — Flexible config file with environment variable overrides and ${VAR} interpolation
• Hot Reload — Watch config file for changes and reload automatically (off by default)
• Background Mode — Run as daemon detached from terminal
• Auto-start on Login — Launch on system startup via launchd (macOS)

Quick Start

1. Install

# macOS / Linux
brew tap routatic/tap && brew install routatic-proxy

# Windows
scoop bucket add routatic https://github.com/routatic/scoop-bucket && scoop install routatic-proxy

# Docker (with Makefile)
cp .env.example .env                    # then put your API key in .env
make docker-up

# Docker (manual)
cp .env.example .env
docker build -t routatic-proxy .
docker run -d --restart unless-stopped --name routatic-proxy --env-file .env -p 3456:3456 routatic-proxy

# Docker from GitHub Container Registry
docker pull ghcr.io/routatic/proxy:latest
docker run -d --restart unless-stopped --name routatic-proxy --env-file .env -p 3456:3456 ghcr.io/routatic/proxy:latest

Or see INSTALLATION.md for more options.

2. Initialize Configuration

routatic-proxy init

Creates a default config at ~/.config/routatic-proxy/config.json. Edit it to add your API key, or set the environment variable:

export ROUTATIC_PROXY_API_KEY=sk-opencode-your-key-here

3. Start the Proxy

routatic-proxy serve

Stop the Docker container (if using Docker):

make docker-stop

4. Configure Claude Code

export ANTHROPIC_BASE_URL=http://127.0.0.1:3456
export ANTHROPIC_AUTH_TOKEN=unused

5. Run Claude Code

claude
