Next.js 16 vs A La Pieter Levels Stack
Real-world performance comparison based on identical SaaS dashboard implementations.
Next.js 16
VPS (Bun)
The React meta-framework running on Bun runtime. Built by Vercel, Next.js supports SSR, SSG, ISR, and streaming—all configured per-route. This variant uses Bun runtime for potentially faster startup times and request handling. The App Router architecture brings React Server Components, nested layouts, and Server Actions. While Bun support for Next.js is unofficial, it works in practice and offers a comparison point for runtime performance. Ideal for teams wanting to benchmark Node.js vs Bun performance with their Next.js applications.
A La Pieter Levels Stack
VPS (PHP)
The indie hacker's PHP stack popularized by Pieter Levels, creator of Nomad List, Remote OK, and Photo AI. This deliberately simple LAMP-style architecture has powered multiple million-dollar bootstrapped products. No build step, no JavaScript framework, no complex deployment—just PHP files served directly. SQLite for the database, jQuery for interactivity where needed, and vanilla CSS. The entire stack fits in a single developer's head. This approach challenges modern web development complexity. It demonstrates that successful products don't require cutting-edge frameworks—they require shipping. Perfect for solo founders and rapid prototyping.
