Mappstack
Claude connectorCommunityDesign and audit software systems as C4 diagrams, data models, API specs and state machines that Claude reads and writes.
Mappstack maps software systems. Claude reads and writes the same map you edit in the Mappstack web editor: C4 diagrams from system context down to code, data models, OpenAPI 3.2 specs, event contracts, job schedules, state machines and business capability maps.
Every save is validated, and Claude can audit a project for gaps before designing the next part.
