Hey HN. I built Corral because every time I asked an AI coding agent to
"add auth and payments," it hallucinated for an hour and produced broken
code. Wrong imports, phantom endpoints, a login page wired to nothing. The problem isn't the agent. It's that auth-to-billing-to-gating is genuinely hard to wire, and there's no machine-readable spec for how to do it. Corral is an open-source CLI (MIT) that gives your agent a spec it can read (llms.txt), then scaffolds auth + Stripe billing into your existing project. It detects your framework (Express, Next.js, Hono, Fastify, and 13+ more), embeds into your existing server (doesn't create a new one), and generates working components: profile page, admin dashboard, plan gating, Stripe checkout, usage metering. One YAML config file controls everything. The agent workflow is 9 commands. Every command supports --json. Errors include a "fix" field. Exit 0 means deploy-ready. I hardened this across 10 framework/DB combos with blind agent tests: 3 AI models, 3 rounds each, then a 10-agent fleet. Found and fixed real edge cases like Express 4 vs 5 route patterns, Vite proxy ordering, and agents creating duplicate servers instead of embedding into existing ones. To try it, paste this into any AI coding agent: GitHub: https://github.com/llama-farm/corral npm: npx create-corral init Docs: https://llama-farm.github.io/corral/ |
