Web Adjuster
Tornado based for customizing other websites

Web Adjuster is a Tornado-based, domain-rewriting proxy for applying custom processing to Web pages. It is particularly meant for users of smartphones etc as these might not support browser extensions. It is self-contained in a single python file.

Web Adjuster can:

  • Add a custom stylesheet to change size, layout and colours
  • Add custom Javascript to all pages, allowing many desktop browser extensions to work as-is on a smartphone or tablet
  • Supply default values of cookies for site preferences etc
  • Run a custom program to change the markup, or to change or annotate text for language tools (see for example Annotator Generator)
  • Render images for a language or text size not supported by the browser (this function requires the Python Imaging Library and suitable fonts)
  • Down-sample MP3 audio to save bandwidth, and add plain text versions of PDF and EPUB files (helper programs are required for these functions)
  • Remove problematic markup from pages

Extension or Plugin

This package can be used as an extension, plugin, or add-on to:
