Svedit

A tiny library for building editable websites in Svelte. It solves the problem of content management by allowing developers to model content in JSON, render it with Svelte components, and edit it directly in the layout, removing the need for a separate CMS. It is designed for developers building Svelte applications, from freelancers to enterprises. It is positioned as a lightweight, Svelte-native alternative to traditional CMSs, with a small footprint and no third-party rendering APIs.
