Can any one to me the difference between HP ALM QC and QA complete ??

Hi,

SmartBear does not provide such comparison information. We are always glad to tell about our products features and peculiarities, but we don't compare our products with other tools from different vendors. You can learn about QAC main features here: https://qacomplete.com/features

BTW, I've googled for such a research, and I found the following resource: https://www.practitest.com/qacomplete_vs_quality_center/
