itwinjs-core

itwinjs-core is an open-source monorepo for the iTwin.js library, providing a comprehensive set of tools and APIs for creating, visualizing, and analyzing digital twins of infrastructure assets. It is designed for developers building custom applications for engineering, construction, and operations, enabling them to work with 3D models, reality data, and geospatial information. The project is interesting because it democratizes infrastructure digital twin technology, offering a powerful, extensible platform that runs in the browser, desktop, or backend, and is backed by Bentley Systems.
