Splash - A javascript rendering service

Splash is a javascript rendering service. It’s a lightweight web browser with an HTTP API, implemented in Python 3 using Twisted and QT5. The (twisted) QT reactor is used to make the service fully asynchronous allowing to take advantage of webkit concurrency via QT main loop. Some of Splash features:

  • process multiple webpages in parallel;
  • get HTML results and/or take screenshots;
  • turn OFF images or use Adblock Plus rules to make rendering faster;
  • execute custom JavaScript in page context;
  • write Lua browsing scripts;
  • develop Splash Lua scripts in Splash-Jupyter Notebooks.
  • get detailed rendering info in HAR format.
