About PageGlass

What PageGlass does

• Serves search engines, AI crawlers and social platforms a fully rendered copy of each page, so your content can be read, indexed, cited and shared.
• Needs one DNS change. There is no code to install and no framework migration.
• Recognises crawlers and AI fetchers, including GPTBot, ClaudeBot, PerplexityBot and Googlebot, and keeps the list current.
• Offers free tools to see what bots receive from any site, such as the What Bots See scanner.

What PageGlass does not do

• It does not change your code, your design or what people see.
• It does not show crawlers different content from people: it serves the same page, already rendered, so it is not cloaking.
• It is not needed if your site already server-renders every page.

How it works

Requests for your domain pass through Cloudflare's edge network. A small worker there recognises crawlers by how they identify themselves. People are passed straight to your site, unchanged. A crawler is given a rendered copy of the page: a headless browser on a dedicated render server loads your page, waits for it to finish, and the result is cached at the edge and refreshed in the background so the crawler's reply is quick.

Cloudflare provides the edge network and the cache, Hetzner provides the render compute (in Germany), and Supabase provides the database and sign-in (in the EU). See how PageGlass compares with Prerender.io or read the JavaScript SEO rendering guide.
