Performance
Both Sapper and Vitepress are known for their performance. Sapper leverages server-side rendering to provide fast initial page loads and optimized client-side hydration. Vitepress, built on top of Vite, a fast build tool, also offers excellent performance with its lightweight and optimized approach to static site generation.
Developer Experience
Sapper provides a comprehensive development experience with features like hot module replacement, code splitting, and server-side rendering. It has a rich ecosystem and supports various plugins and integrations. Vitepress, on the other hand, focuses on simplicity and ease of use.

Customization
Sapper allows for more customization options as it is a full-featured framework. It provides flexibility in terms of routing, server-side rendering configuration, and integration with other libraries. Vitepress, being a specialized static site generator, has a more opinionated structure and limited customization options. It is designed to work out of the box for documentation sites.
Community and Ecosystem
Sapper has a larger and more established community with a wide range of plugins, tutorials, and resources available. It benefits from the popularity of Svelte, its underlying framework. Vitepress, being a newer project, has a smaller community but is growing steadily. It has a focused ecosystem with plugins and themes specifically tailored for documentation websites.
