Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM.
Svelte is an MIT-licensed open source project with its ongoing development made possible entirely by fantastic volunteers. If you'd like to support their efforts, please consider:
React is a popular JavaScript library for building user interfaces. It uses a virtual DOM for efficient updates, and it's known for its component-based architecture. Unlike Svelte, React requires a runtime library and often involves more boilerplate code.
Vue is a progressive JavaScript framework used for building UIs and single-page applications. It is similar to Svelte in its component structure and reactivity model but differs in that it uses a virtual DOM and requires a runtime.
Angular is a platform and framework for building single-page client applications using HTML and TypeScript. It is more prescriptive than Svelte, with a complex ecosystem and a steep learning curve, and it includes features like dependency injection and RxJS integration.
Preact is a fast, 3kB alternative to React with the same modern API. It provides a similar component-based architecture but with a smaller footprint. Preact is closer to Svelte in terms of size but still operates with a virtual DOM.

The planned feature introduces a review step before releases go live, following the Shai-Hulud attacks and a rocky migration off classic tokens that disrupted maintainer workflows.
