Link: Deeploy Helper
Deeploy Helper is a simple module to make our lives as EE developers just a little easier. It collects many of the configuration parameters we most frequently modify on one page, where power users can modify them all at once.
Deeploy Helper is a life saver for the less-than-ideal configuration set up of ExpressionEngine. Just upload, install, and you have access to all of the absolute paths and URLs on one single page. There is even a search and replace feature to make it more simple. A must-have tool for going from development to production. Works in both EE1.7.* and EE2.*.
