I'm looking into expanding my business through the offer of an update service for CMS's (I've been asked about such a service, so I thought why not?) The problem I've had so far is not with the updating, but rather verifying if the update broke anything on the updated site.
Does anyone know of a crawler/anything that could scrape the site on demand and compare the before and after to report website changes????
The service is aimed at customers that have upgradable sites (no core mods in either the plugins or the CMS itself). But that is beside the point, what I'm looking for is some sort of software that could crawl the site before and after the upgrade to check for differences and report if there are so I can revert in case of problems.
