Run Claude Code Free with OpenRouter in 5 Minutes

Chapters / key moments (click to jump — plays here on the page)

A free open-source middleware project lets you plug any model from OpenRouter — including free-tier options — into Claude Code in about five minutes. The setup installs a proxy helper with a single command, connects it to OpenRouter via a free API key, and then Claude Code runs normally against whatever model you've pointed it at.

Key Takeaways

A free middleware proxy sits between Claude Code and OpenRouter, translating Claude Code's API calls to whichever model you select.
Setup is five steps: install the helper, open the control panel, plug in an OpenRouter API key (free tier available), and launch Claude Code.
Works with any OpenRouter model — free options like open-source models are valid targets, though quality will vary versus Claude Sonnet or Opus.
Pairing with an agent OS dashboard lets you preview built projects, manage sessions, and chat with your agent from a single interface.
Practical use cases include building websites, landing pages, tools, and client work without a paid Anthropic subscription.

How the Proxy Works

Claude Code expects to talk to Anthropic's API. The middleware intercepts those calls locally and forwards them to OpenRouter instead, which routes to your selected model. From Claude Code's perspective, nothing has changed — it still sends the same requests and gets back the same structured responses. The proxy handles the translation transparently.

The tradeoff is model quality. Claude Code is optimized for Anthropic models and will perform best with them. Free OpenRouter models may produce lower-quality code completions, miss context, or make more errors. This approach is most useful for experimenting with Claude Code's interface before committing to a subscription, or for lower-stakes tasks where cost sensitivity outweighs output quality.

What You Can Build

Even with a free model backend, Claude Code's agentic loop — file reading, editing, running commands, iterating — is fully functional. Websites, landing pages, scripts, content tools, and client deliverables are all viable. The limitation is in the model's reasoning depth, not in Claude Code's capabilities as a framework.
