+# ⚡ Full-Stack Next.js + Cloudflare Template
 
 A production-ready template for building full-stack applications with Next.js 15 and Cloudflare's powerful edge infrastructure. Perfect for MVPs with generous free tiers and seamless scaling to enterprise-level applications.
 
 **Inspired by the [Cloudflare SaaS Stack](https://github.com/supermemoryai/cloudflare-saas-stack)** - the same stack powering [Supermemory.ai](https://git.new/memory), which serves 20k+ users on just $5/month. This template modernizes that approach with Cloudflare Workers (vs Pages), includes comprehensive D1 and R2 examples, and provides a complete development workflow.
