Lupin

Claude Code, on any model.
The gentleman router: it borrows the Claude Code harness and lends it to other models.

[![CI](https://github.com/Fanfulla/Lupin/actions/workflows/ci.yml/badge.svg)](https://github.com/Fanfulla/Lupin/actions/workflows/ci.yml) [![License: Apache-2.0](https://img.shields.io/badge/license-Apache--2.0-blue.svg)](LICENSE) ![Node >= 20](https://img.shields.io/badge/node-%E2%89%A5%2020-brightgreen) ![TypeScript strict](https://img.shields.io/badge/TypeScript-strict-3178c6) ![tests](https://img.shields.io/badge/tests-873%20node%20%2B%20135%20rust-success)

Your whole setup lives in Claude Code, not in the model: MCP servers, skills, `CLAUDE.md`, hooks, memories, plugins. But Claude Code speaks one protocol, the Anthropic Messages API, so trying another model means changing tool and starting over.

**Lupin changes the model. Nothing else moves.**

Prerequisites

Required	Why
Node.js 20 or newer	runs the proxy and CLI
Claude Code on the PATH as `claude`	the harness Lupin launches
One provider API key, subscription, or local runtime	the model that will answer
Rust toolchain, optional	only for the terminal dashboard
