Here are a few pieces of open source software that would fall into the category of website accessories. To date, I haven’t come across very many of these but will that change?
This is a web-based code editor that you can host on your own website. The concept has me wondering if it wise to go making code changes to a live website without testing them offline first but it sounds interesting for those times when you are carrying over tested code or need to fix a glitch in an implementation.
A PHP library for re-using RSS feeds in web content.
The point of this tool is to manage advertising. While that means that I may never get to using it, that’s never to say that there aren’t others who might.
This is something that I use: a self-hosted website analytics engine. Using Google Analytics and Woopra is all very fine but they are implemented using JavaScript scripts hosted on other parts of the web and that can slow down page loading as well as giving blockers of JavaScript something else to do. The latest version may not work on the servers hosting websites for me but, given that the previous provides all that I need, there’s no incentive in upgrading.
