SitecoreDXG: The Documentation Experience Generator
Sitecore template architecture visualization and documentation tool from the SitecoreUML family. Leveraging the open-source APIs associated with StarUML (on which SitecoreUML is also based), SitecoreDXG provides support for generating template data model architecture diagrams and HTML documentation from any existing Sitecore instance (PaaS and non-PaaS both supported) that has the SitecoreUML Service for Sitecore.
