Metered Template

Next.js SaaS template for products that charge by usage — API calls, storage, email sends. Two plans (Starter, Pro) with included usage amounts per feature.

Usage above the included limits is billed as overage at the end of each billing period. Your customers keep a predictable base price and pay more only when they use more.

Stack: Next.js 16, Better Auth, Drizzle ORM, PostgreSQL, Commet SDK
