Cheminformatic analysis has been an active field for almost half a century, with considerable innovation accelerating drug discovery. However, the requirement for programming expertise prevents its popular use, often necessitating collaboration between multiple disciplines to integrate cheminformatics tasks into drug discovery pipelines. Various efforts have been made to mitigate this issue at the cost of cross-platform compatibility and preservation of data privacy. We introduce a static web application, QSAR, Quantitative Structure-Activity Relationship In The Browser (QITB), that performs various cheminformatic analyses on the user’s device, with no external server required. It includes tools to access the publicly available ChEMBL database and tools for users to upload their own data. It automatically processes data, offers a range of interactive tools for data visualisation and analysis, and supports the training and evaluation of lightweight machine learning models. By being hosted on GitHub Pages, the QITB web app is broadly accessible and enables the use of cheminformatics by experts and non-experts alike.
