Coding Capybaras is a production-ready starter kit for developers who use AI coding tools like Claude Code, Cursor, Codex, or Copilot. It ships with auth, billing, and email pre-configured on a Next.js + Supabase + Stripe stack, so you skip the setup grind and start building features on day one. The key differentiator is 114 integration guides formatted as copy-paste prompts your AI assistant can execute directly — no hallucinated file structures or half-baked scaffolding. The base stack is free to use with $0 monthly running costs. A one-time $97 Pro upgrade unlocks a marketplace and additional features.
