CCX is a high-performance AI API proxy and protocol translation gateway for Claude, OpenAI Chat / Codex Responses, and Gemini. It provides a unified entrypoint, built-in web administration, failover, multi-key management, channel orchestration, and model routing.

• Integrated backend + frontend architecture with single-port deployment
• Dual-key authentication with PROXY_ACCESS_KEY and optional ADMIN_ACCESS_KEY
• Web admin console for channel management, testing, and monitoring
• Support for Claude Messages, OpenAI Chat Completions, Codex Responses, and Gemini APIs
• Protocol conversion across Claude Messages, OpenAI Chat, Gemini, and Responses
• Smart scheduling with priorities, promotion windows, health checks, and circuit breaking
• Per-channel API key rotation, proxy support, custom headers, and model allowlists
• Model remapping, fast mode, and verbosity controls
• Streaming and non-streaming support
• Responses session tracking for multi-turn workflows

Visual channel management with drag-and-drop priority adjustment and real-time health monitoring.

Supports multiple upstream service types (Claude/Codex/Gemini) with flexible API key, model mapping, and request parameter configuration.

Real-time monitoring of request traffic, success rate, and response latency per channel.

CCX exposes one backend entrypoint:

Client -> backend :3000 ->
  |- /                    -> Web UI
  |- /api/*               -> Admin API
  |- /v1/messages         -> Claude Messages proxy
  |- /v1/chat/completions -> OpenAI Chat proxy
  |- /v1/responses        -> Codex Responses proxy
  |- /v1/models           -> Models API
  `- /v1beta/models/*     -> Gemini proxy

Key properties:

• Single port
• Embedded frontend assets
• No separate reverse proxy required
• Admin and proxy traffic can use different keys

See ARCHITECTURE.md for detailed design notes.

1. Download the latest binary from Releases
2. Create a .env file next to the binary:

PROXY_ACCESS_KEY=your-super-strong-secret-key
PORT=3000
ENABLE_WEB_UI=true
APP_UI_LANGUAGE=en

3. Run the binary and open http://localhost:3000

docker run -d \
  --name ccx \
  -p 3000:3000 \
  -e PROXY_ACCESS_KEY=your-super-strong-secret-key \
  -e APP_UI_LANGUAGE=en \
  -v $(pwd)/.config:/app/.config \
  crpi-i19l8zl0ugidq97v.cn-hangzhou.personal.cr.aliyuncs.com/bene/ccx:latest

git clone https://github.com/BenedictKing/ccx
cd ccx
cp backend-go/.env.example backend-go/.env
make run

Useful commands:

make run
make dev
make build

Set the default admin UI language with:

APP_UI_LANGUAGE=en

Supported values:

• en
