Prerender is a node server that uses Headless Chrome to render HTML,
screenshots, PDFs, and HAR files out of any web page. The Prerender
server listens for an http request, takes the URL and loads it in
Headless Chrome, waits for the page to finish loading by waiting for
the network to be idle, and then returns your content.
You can choose wheter to expose it as a web app, or not.
