Pupper

Pupper is a simplified fork of jclvicerra/puppeteer-prerender web page prerenderer service based on Puppeteer(Chrome headless node API). Which is almost ready to use in production (actually we are already using it :) ).

Useful server side rendering through proxy. Outputs only HTML (if you need PDF on PNG consider forking this project or use the original).

Features

  • docker and k8s ready

  • Limiting concurrent requests

  • Pupper uses Redis as cache backend

  • Has a blacklist of domains to ignore while rendering pages (e.g. metrics, stats, trackers, etc)

  • Correct status codes for crawlers (using <meta name="prerender-status-code" content="404">)

  • and other ...
