Business Intelligence (BI) and Data Analytics are among the top Data Science topics nowadays. They are available as Self-Service solutions of valuable utility when business professionals need to perform data visualization and/or analytics. In addition to that, a great opportunity for companies to start exploring their data with minimal or no assistance from IT technicians. In other words, a shortcut to business opportunities. In this paper, through the OSSPal methodology, we assess the free versions of three popular Self-Service BI and Analytics tools: Power BI, QlikView, and Tableau Public. In conclusion, we could see that Power BI offers more features at no cost, being so highly recommended for Small and Medium-Sized Enterprises (SMEs). On the other hand, QlikView and Tableau Public were considered almost as powerful as Power BI and might also naturally be a more suitable choice according to the requirements of a company.
