VIZid Suite is built on an open Blender fork and a set of separate, proprietary tools that talk to it across process and network boundaries. Here's how each part is licensed.
The Blender 5.1 fork (custom editors, branding, mesher integration) and the VIZid Gloss / VIZid Mesh / VIZid Cosmos add-ons are derivative works of Blender and ship under GPL-2.0-or-later, with source available. VIZid may still distribute compiled binaries.
The VIZid Mesh converter, the mediator / backend, VIZid Flow render server & node, the shared security library, and the Creo and SolidWorks VIZid Bridge plugins are separate programs that communicate only across process/network boundaries — they remain closed and proprietary.

Blender at runtime, so they are copyleft. The converter, services and CAD plugins
are independent programs that exchange data over the CLI, sockets and files — GPLv2/v3
(unlike AGPL) does not reach across that boundary, so they stay proprietary.
VIZid Suite redistributes excellent third-party libraries under their own
licenses, including Open CASCADE Technology (OCCT), the Autodesk FBX SDK,
NVIDIA CUDA / OptiX, FFmpeg and others. Full attributions ship with the app
in THIRD_PARTY_NOTICES.txt.
