Quick Overview
Next.js Subscription Payments Starter
nextjs‑subscription‑payments is a starter template built on Next.js, integrating backend and billing essentials: user auth, database, and subscription payments designed to help you quickly spin up a SaaS or membership‑based web application.

On the backend it offers integration with Firebase (Firestore, Functions, hosting, realtime updates) and optional AI/ML capabilities via Vertex AI useful if you plan AI‑powered features. For monetization or SaaS‑style apps, it supports payments: mobile IAP/subscriptions via RevenueCat and web payments via Lemon Squeezy. It also includes support for notifications, analytics/monitoring, feedback, offline‑ready data handling, and optional templates (for example UI templates, landing‑page/marketing‑page templates, even Tinder‑style or chatbot‑style UIs) enabling you to ship full‑featured apps quickly.
