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…

Today, the apps we build use a LOT of APIs, including Stripe for payments, Clerk for auth, Twilio for messaging and more. But receiving these webhook events to keep our own data synchronized has traditionally been a big hassle. The problem applies to both prod and dev. In prod, we need a reliable way to subscribe to these events and deliver them to their eventual destination. In dev, we need a way to test against these events locally. The existing products in this space include ngrok, HookDeck, Convoy and others. They are all great, but they have some caveats. For one, ngrok doesn't provide…
