Svelte REPL vs SvelteKit

Svelte REPL is a free web playground for trying Svelte, a UI framework for building web projects. Svelte compiles components written in HTML, CSS and JavaScript into optimized JavaScript. The Playground offers examples covering reactivity, props, logic, events, bindings, stores, transitions, SVG and component composition.

Svelte can be used for projects ranging from standalone components to full-stack apps built with SvelteKit, its companion application framework. The framework is focused on web development, and the listed runtime scope is frontend. Svelte is free and open-source software under the MIT license. The Playground page offers GitHub login, while the saved apps page requires users to log in to view saved apps. For newcomers, Svelte recommends its interactive tutorial. Its documentation points to StackBlitz for a more fully featured environment. The project also directs users to Svelte Society and its Discord server for community. Svelte says the framework is developed by full-time and part-time maintainers and backed by Vercel and donors.
