vkstack

Unofficial. Not affiliated with or endorsed by Broadcom. The data here comes from the same undocumented endpoint the interoperability matrix website calls, so it can change or stop working without notice. The matrix itself is the authority — verify anything you are relying on at interopmatrix.broadcom.com.

Pick a version at any layer. Everything that can be in the same working stack stays lit; everything that cannot fades back. Hover a connection, or a version in the map, to trace what it joins.

Click any version to branch from it. Lit versions can be in a stack with your selection; faded ones cannot.

Lit means a complete valid stack exists containing both that version and your selection — not just that two products happen to list each other. Supervisor, VKS and VKr are grouped by version line; vCenter is not, because its patch letter changes what it supports. A grouped node stands for several releases and clicking it selects the newest — hover to see which, and the rest. Where the matrix hedges, so does the picture: dashed means upstream lists the combination compatible without testing it, dotted means it published no result for that pair at all and the connection is inferred from the rest of the stack.
