SaaS starter: Next.js + Supabase + Stripe that builds

Ask your AI coding agent for a Next.js + Supabase + Stripe SaaS starter and get a project that installs and builds, with login, checkout and a webhook already wired.

Paste this into your agent

Use the BotKelp MCP to scaffold a Next.js SaaS starter with Supabase login and Stripe checkout. Call get_help first, pick catalog ids, then purchase_scaffold. Do not invent ids.
