TanStack Start vs A La Pieter Levels Stack
Real-world performance comparison based on identical SaaS dashboard implementations.
TanStack Start
VPS
A full-stack React framework from the creators of TanStack Query, Table, and Router. Built on Vinxi (a Vite-based meta-framework engine), TanStack Start brings the TanStack philosophy of type-safety and developer experience to server rendering. Features isomorphic data fetching with TanStack Router's loader patterns, full-stack type safety from database to component, and first-class support for server functions. The router provides file-based routing with powerful search param management. Still in beta but rapidly maturing, TanStack Start appeals to developers who love TanStack Query's patterns and want them extended to the full stack.
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.
