After the work of Pederson, Lehn and Cram in the second half of the 20th century (nobel prize in 1987 "for their development and use of molecules with structure-specific interactions of high selectivity"), supramolecular chemistry has become a popular field of research. The experimental determination of association constants utilising supramolecular titration experiments plays a big role in the analytical zoo of this research area. Several software packages have been written in the last three decades, each having its own strength and weaknesses. In times of open science, open data and open source software, some of these older software solutions might be considered as not state-of-the-art. The most recent tool for supramolecular titration experiments has been developed by the group of Thordarson and is available via www.supramolecular.org (last checked 17.01.2022) as online service. As a matter of taste, someone could prefer online tools to offline applications and vice verse. As an alternative to the older offline applications and as well as to the online tools, a newly written software package for supramolecular titration experiments called SupraFit is reported.
