Claudin

A coding-agent CLI that works across multiple model providers — Anthropic, OpenAI, Gemini, Mistral, xAI Grok, GitHub Copilot, ChatGPT, Ollama, LM Studio, Bedrock, Vertex, Foundry, Azure, and 15+ OpenAI-compatible aggregators — with one consistent terminal workflow.

Install

npm install -g @claudiolabs/claudin@latest

Requires Node 20+. Works on Linux, macOS, and Windows.

Quick Start

claudin

On first run, Claudin opens the /provider wizard. Pick a preset, enter credentials, and start working — no environment variables required.

Providers

Configure from inside the REPL with /provider:

• Anthropic — API key or OAuth
• OpenAI — API key or any OpenAI-compatible base URL
• OpenAI-compatible aggregators — OpenRouter, Together, Groq, DeepSeek, Moonshot / Kimi, Alibaba DashScope (CN + Intl / Qwen), MiniMax, NVIDIA NIM, Atomic Chat, Bankr, opencode Zen, opencode Go
• Google — Gemini (API key, ADC, or OAuth)
• Mistral — API key
• ChatGPT — Codex OAuth
• xAI — Grok (device-flow OAuth)
• GitHub — Copilot (device flow)
• Microsoft — Azure OpenAI
• Local — Ollama, LM Studio
• Cloud — AWS Bedrock, Google Vertex AI, Azure AI Foundry
• Custom — any OpenAI-compatible endpoint

Run /provider doctor to check your active profile, or /provider migrate to import a legacy ~/.claude/ config.
