Vibe coding with Claude Code on free relay credits

"Vibe coding" = you describe what you want, the agent writes and runs it. With Claude Code on a free relay station's credits, you can do it without paying for the official API.

Connect in two env vars (AgentRouter as the example):

export ANTHROPIC_BASE_URL="https://agentrouter.org"
export ANTHROPIC_AUTH_TOKEN="sk-****your-key****"

Then just talk to it. Open an empty folder and say:

Build a todo app with Vite + React, local storage, and a dark mode.

Claude Code scaffolds the files, installs deps, runs it. You keep going in plain language — "add a tag filter", "make this green". Out of credit? Check in daily for more, or switch to another station.

These relay stations are free (signup + check-in credit), so grab a few. List with models and tested dates: AI relay station list

The signup links carry my referral param; strip ?aff= if you'd rather not.
