Leptos vs A La Pieter Levels Stack

Real-world performance comparison based on identical SaaS dashboard implementations.

Leptos

Leptos

VPS (Rust)

View Live Demo

A full-stack Rust framework using fine-grained reactivity. Leptos compiles to WebAssembly for near-native browser performance, with server functions that run seamlessly on the backend. The framework's signal-based reactivity (similar to SolidJS) enables surgical DOM updates without a virtual DOM. Server functions provide RPC-like calls with full type safety between client and server. Leptos can render on the server and hydrate on the client. For Rust developers, Leptos offers a compelling way to build web applications with the safety and performance guarantees Rust is known for. The learning curve is steep but the results are impressive.

A La Pieter Levels Stack

A La Pieter Levels Stack

VPS (PHP)

View Live Demo

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.
