## What it is
Elder.js is an opinionated static site generator and web framework for Svelte built with SEO in mind, supporting both static site generation and SSR. It features build hooks, community plugins, shortcodes, and partial hydration to keep client-side JavaScript payloads minimal.

## Use cases
- build a fast SEO-optimized static site with Svelte
- generate thousands of pages quickly with a parallelized build
- ship pages with 0KB JavaScript by default
- partially hydrate only interactive components on the client
- migrate from Sapper to a maintained alternative
- fetch data from multiple sources for Svelte templates

## When to choose
- you want an SEO-first Svelte framework with tiny bundles
- you need to build large data-intensive static sites fast
- you want fine-grained control over the page generation pipeline via hooks

## When to avoid
- you want a framework with a large active community and frequent releases
- you need full SPA-style client-side routing
- you prefer a framework-agnostic or React/Vue ecosystem
