I've used https://structurizr.com https://structurizr.com for that purpose before. It allows you to define the elements (containers, users, etc.) separately from the diagrams and then pull them into various views of the system. My workflow is something like this: - define the elements at various zoom levels https://structurizr.com/share/1/explore/tree https://structurizr.com/share/1/explore/tree - define the relations https://structurizr.com/share/1/explore/component-dependencies https://structurizr.com/share/1/explore/component-dependenci... - create diagrams by selecting subsets of what was defined in the first two steps https://structurizr.com/share/36141/diagrams#SystemLandscape https://structurizr.com/share/36141/diagrams#SystemLandscape
