    Improves SEO

Rendertron is designed to enable your Progressive Web App (PWA) to serve the
correct content to any bot that doesn't render or execute JavaScript. Rendertron
runs as a standalone HTTP server. Rendertron renders requested pages using
Headless Chrome, [auto-detecting](#auto-detecting-loading-function) when your
PWA has completed loading and serializes the response back to the original
request. To use Rendertron, your application configures
[middleware](#middleware) to determine whether to proxy a request to Rendertron.
Rendertron is compatible with all client side technologies, including
[web components](#web-components).

## Demo endpoint

are no uptime guarantees.
