CLUSTER UML-DIAGRAMS-CREATING · 15 ENTRIES · EARLIEST ENTRY 2007-04-09

UML diagramming tools

This cluster consists of desktop and web applications for creating UML and related diagrams, often with code generation or architecture modeling. Dated entries appear sporadically from 2007 to 2026 with no clear trend, starting with a single entry in 2007 and then occasional entries across years. Traction leaders are CASE_UML, Umbrello, and violetumleditor, each showing zero stars as their activity signal.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
