Prerender.io – Lovable (Cloudflare Worker)

A Cloudflare Worker that proxies your Lovable app and routes bot traffic through Prerender.io for SEO rendering.

How it works

• Regular users are proxied transparently to your Lovable app (LOVABLE_UPSTREAM)
• Search engine bots and crawlers are routed to Prerender.io for server-side rendered HTML
• Canonical tags are injected/replaced to point to the public URL
• Redirects from the upstream are rewritten to use your public hostname

Setup

1. Deploy worker.js as a Cloudflare Worker
2. Set the following environment variables in your Worker settings:

Variable	Description
LOVABLE_UPSTREAM	Your Lovable app URL (e.g. https://yourapp.lovable.app)
PRERENDER_TOKEN	Your Prerender.io token

Requirements

• Cloudflare Workers (supports HTMLRewriter)
