GitHub 57K Star Viral Tool: Use Claude Code for Free with free-claude-code

GitHub 57K+ Stars Trending Tool: How to Use Claude Code for Free via Open-Source Proxy

by

Anthropic’s official CLI agent, Claude Code, has revolutionized AI-assisted programming with its deep repository understanding and terminal execution capabilities. However, heavy usage can quickly lead to high API token costs for individual developers and solo creators.

The viral open-source project free-claude-code (with over 57,000 Stars on GitHub) solves this problem. By running a local API proxy on your machine, it routes Claude Code’s requests to over 60 free-tier AI providers and models—allowing you to enjoy unlimited AI coding agent capabilities without incurring Anthropic API fees.

How It Works: Local Reverse Proxy Architecture

The core concept behind free-claude-code is to decouple the Claude Code client interface from Anthropic’s paid backend.

Claude Code Terminal (CLI) ──► Local Proxy Server ──► 60+ Free Model Providers (e.g., NVIDIA NIM, DeepSeek, Groq)
  1. Local Proxy Interception: The tool runs a lightweight local proxy server that intercepts outgoing API requests generated by Claude Code.
  2. Request Rerouting: Instead of reaching Anthropic’s billing endpoints, the proxy routes the requests to free API providers (such as NVIDIA NIM, DeepSeek, Groq, OpenRouter, and others).
  3. Seamless Protocol Translation: It handles context format adaptation and response streaming behind the scenes, allowing Claude Code to operate as if connected to its official backend.

Quick Setup & Installation Guide

You can set up the proxy on your development machine in three simple steps:

1. Installation

Run the official installer in your terminal:

  • macOS / Linux: Bashcurl -fsSL "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.sh" | sh
  • Windows (PowerShell):PowerShell& ([scriptblock]::Create((irm "https://raw.githubusercontent.com/Alishahryar1/free-claude-code/main/scripts/install.ps1")))

2. Configure Free API Keys

Launch the server (e.g., fcc-server on Linux or via the desktop app on macOS/Windows). Open the Admin UI URL shown in your terminal log and paste your free API key (such as a free NVIDIA NIM API Key or OpenRouter key).

3. Run Claude Code via the Proxy

Launch Claude Code routed through the local proxy:

Bash
