Claudex is a unified proxy that lets Claude Code seamlessly work with multiple AI providers through automatic protocol translation.

Features

• Multi-provider proxy — DirectAnthropic passthrough + Anthropic <-> OpenAI Chat Completions translation + Anthropic <-> Responses API translation
• 20+ providers — Anthropic, OpenRouter, Grok, OpenAI, DeepSeek, Kimi, GLM, Groq, Mistral, Together AI, Perplexity, Cerebras, Azure OpenAI, Google Vertex AI, Ollama, LM Studio, and more
• Streaming translation — Full SSE stream translation with tool call support
• Circuit breaker + failover — Automatic fallback to backup providers with configurable thresholds
• Smart routing — Intent-based auto-routing via local classifier
• Context engine — Conversation compression, cross-profile sharing, local RAG with embeddings
• OAuth subscriptions — ChatGPT/Codex, Claude Max, GitHub Copilot, GitLab Duo, Google Gemini, Qwen, Kimi
• Configuration sets — Install and manage reusable Claude Code configuration sets from git repos
• TUI dashboard — Real-time profile health, metrics, logs, and quick-launch
• Self-update — claudex update downloads the latest release from GitHub

Installation

# One-liner (Linux / macOS)
curl -fsSL https://raw.githubusercontent.com/StringKe/claudex/main/install.sh | bash

# From source
cargo install --git https://github.com/StringKe/claudex

# Or download from GitHub Releases
# https://github.com/StringKe/claudex/releases

System Requirements

• macOS (Intel / Apple Silicon) or Linux (x86_64 / ARM64)
• Claude Code installed
• Windows: download pre-built binary from Releases

Quick Start

# 1. Initialize config
claudex config init

# 2. Add a provider profile interactively
claudex profile add

# 3. Test connectivity
claudex profile test all

# 4. Run Claude Code with a specific provider
claudex run grok

# 5. Or use smart routing to auto-select the best provider
claudex run auto

How It Works

claudex run openrouter-claude
    │
    ├── Start proxy (if not running) → 127.0.0.1:13456
    │
    └── exec claude with env vars:
        ANTHROPIC_BASE_URL=http://127.0.0.1:13456/proxy/openrouter-claude
        ANTHROPIC_AUTH_TOKEN=claudex-passthrough
        ANTHROPIC_MODEL=anthropic/claude-sonnet-4
        ANTHROPIC_DEFAULT_HAIKU_MODEL=...
        ANTHROPIC_DEFAULT_SONNET_MODEL=...
        ANTHROPIC_DEFAULT_OPUS_MODEL=...

The proxy intercepts requests and handles protocol translation:

• DirectAnthropic (Anthropic, MiniMax, Vertex AI) → forward with correct headers
• OpenAICompatible (Grok, OpenAI, DeepSeek, etc.) → Anthropic → OpenAI Chat Completions → translate response back
• OpenAIResponses (ChatGPT/Codex subscriptions) → Anthropic → Responses API → translate response back

Configuration

Claudex searches for config files in this order:

1. $CLAUDEX_CONFIG environment variable
2. ./claudex.toml or ./claudex.yaml (current directory)
3. ./.claudex/config.toml
4. Parent directories (up to 10 levels)
5. ~/.config/claudex/config.toml (global, recommended)

Supports TOML and YAML formats. See config.example.toml for the full reference.

# GitHub Copilot
claudex auth login github --profile copilot

# GitHub Copilot Enterprise
claudex auth login github --profile copilot-ent --enterprise-url company.ghe.com

# GitLab Duo (reads GITLAB_TOKEN env)
claudex auth login gitlab --profile gitlab-duo

# Check status
claudex auth status

# Run with subscription
claudex run codex-sub

Model Slot Mapping

Map Claude Code's /model switcher (haiku/sonnet/opus) to any provider's models:

[[profiles]]
name = "openrouter-deepseek"
provider_type = "OpenAICompatible"
base_url = "https://openrouter.ai/api/v1"
api_key = "sk-or-..."
default_model = "deepseek/deepseek-chat-v3-0324"

[profiles.models]
haiku = "deepseek/deepseek-chat-v3-0324"
sonnet = "deepseek/deepseek-chat-v3-0324"
opus = "deepseek/deepseek-r1"
