This article shows the comparison between SPCAF and MSOCAF.
The Microsoft SharePoint Online Code Analysis Framework (MSOCAF) is a free code analysis tool to check your sandboxed solutions for SharePoint Online. It supports only a limited number of checks (mostly included FxCop and SPDisposeCheck), does only support WSPs, created for SharePoint 2010 or earlier and provides only very limited quality assurance, sometimes even false and misleading.
Please have a look at our pre-production page for a demo of SPCAF.
