Preact vs. React vs. SvelteKit vs. Vue.js Comparison Chart

Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.

SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. It addresses common development challenges by providing solutions for routing, server-side rendering, data fetching, service workers, TypeScript integration, and more. SvelteKit apps are server-rendered by default, offering excellent first-load performance and SEO benefits, but can transition to client-side navigation to enhance user experience. The framework is designed to grow with developers, allowing them to start simple and add new features as needed. SvelteKit leverages Vite for a fast and feature-rich development experience, including hot module replacement. In short, Svelte is a way of writing user interface components, like a navigation bar, comment section, or contact form, that users see and interact with in their browsers. The Svelte compiler converts your components to JavaScript that can be run to render the HTML for the page and to CSS that styles the page.
