About Understand-Anything
Understand Anything is an open source TypeScript project, released under the MIT license and developed by Egonex from an original creation by Lum1104.

The project analyzes a codebase through a multi agent pipeline that extracts every file, function, class and dependency, then builds a knowledge graph which it presents in an interactive dashboard. A hosted live demo is available on the project homepage for anyone who wants to pan, zoom, search and explore without running the analysis locally.…
