Ship a usage-based SaaS product in days, not months. This starter includes everything you need to implement Stripe’s modern Billing Meters system—the current standard that replaces deprecated approaches. Start your users free for the first 20 API requests, then bill each call automatically with no artificial limits.

Built on Next.js 14 with Prisma, NextAuth, and Tailwind. Includes secure API key storage (Stripe and AWS-style), a working metered billing endpoint, complete Stripe integration, and SQLite for instant local development. No hidden vendor costs—your metering is pure infrastructure.
