Abstract Chemical Entities of Biological Interest (ChEBI) is a high-quality, manually curated, and open-access database and ontology of chemical entities available online at https://www.ebi.ac.uk/chebi/. The chemical entities in question are either naturally occurring compounds or synthetic compounds that play a vital role in the processes of living organisms. ChEBI was launched in 2004, and over the years the original codebase has become increasingly difficult to maintain. Here, we describe the complete overhaul and modernization of ChEBI’s infrastructure, including its codebase and associated tools (website, web services, and submission tool) to ensure the continued availability and growth of this critical resource for the global bioinformatics community and beyond. The infrastructure overhaul also enabled us to introduce new features and capabilities into ChEBI as well as to update or deprecate redundant ones.
