Listed below are some good examples of high-performance CAQDAS platforms that are free of charge. Some have graphical user interfaces (GUI) and others do not. Some investigation will be required to determine what will best suite your needs. Note that two of these free programs, Aquad and RQDA, make use of the powerful statistical analysis package R. While there is only a plug-in for Aquad, you will need to install R to use RQDA. R is free to download and supported by a vast user community.
Please see the Introduction to R Library Guide for more information on getting started with R.
