What Prerender.io is
Prerender.io renders JavaScript pages as HTML for crawlers, search engines, and AI platforms. It detects crawler requests, loads each page in a headless browser, stores the result, and serves cached HTML while regular visitors use the website normally. Rendered pages can include metadata, Open Graph tags, structured data, and internal links. The service works independently of frontend framework, including React, Vue, Angular, and other JavaScript frameworks. Integration guides cover Cloudflare, Node.js and Express, Nginx, Apache, IIS, Docker, Firebase, Magento, Django, and Spring. Customers can set cache freshness, use scheduled crawls, and access an API. Plans include 30,000 renders for Starter at $59 a month, 100,000 for Growth at $169 a month, and 500,000 for Pro at $419 a month. Starter has a 30-day free trial. Traffic is TLS-encrypted, but cached HTML is not encrypted at rest.
