## Description

react-snap is a static site generator and single-page application prerenderer. It converts dynamic client-side components into static HTML files using a headless browser to improve search engine optimization and initial load speeds.

The project features a headless browser crawler that automatically discovers application routes by following internal links. It includes a hydration optimizer that captures application state and caches network responses during the rendering process, embedding them directly into the HTML to synchronize the client-side application without re-fetching data.

The tool provides a suite of performance optimizations, including critical CSS inlining, asynchronous script loading, and the generation of resource manifests and preload headers. It also supports parallel rendering execution across concurrent browser tabs and can block third-party requests to prevent external scripts from triggering during the build process.
