Programmatic web browsing module with AJAX support for Python

branch: master


Spynner is a stateful programmatic web browser module for Python. It is based upon PyQT and WebKit. It supports Javascript, AJAX, and every other technology that !WebKit is able to handle (Flash, SVG, ...). Spynner takes advantage of JQuery. a powerful Javascript library that makes the interaction with pages and event simulation really easy.

Using Spynner you would able to simulate a web browser with no GUI (though a browsing window can be opened for debugging purposes), so it may be used to implement crawlers or acceptance testing tools.

  • Python >=26

  • Libxml2 / Libxslt libraries and includes files for lxml
  • autopy which in turns need xtst lib & headers on linux (aka Xtest)

  • Throught regular easy_install / buildout:

    easy_install spynner

Running Spynner without X11

  • Spynner needs a X11 server to run. If you are running it in a server without X11. You must install the virtual Xvfb server. Debian users can use the small wrapper (xvfb-run). If you are not using Debian, you can download it here:

    xvfb-run python
  • You can also use tightvnc, which is the solution of the actual maintainer [kiorky].
