Should software companies restrict access to development tools to only their approved business partners?
Broadcom removed public download pages for the VMware Virtual Disk Development Kit on August 25, 2026. The toolkit is now available only to participants in the Technology Alliance Program.
Why it matters
The change restricts access to software required for interacting with virtual disk files in the VMDK format. Broadcom maintains the move is an enforcement of existing license terms for the independently licensed kit.
The Virtual Disk Development Kit (VDDK) is a library enabling developers to access virtual disk files in the proprietary VMDK format. Access is now gated behind the Technology Alliance Program rather than being available via public portal.
The players
Broadcom
A global technology company that designs, develops, and supplies a broad range of semiconductor and infrastructure software products.
VMware
A provider of cloud computing and virtualization technology products now operating as a subsidiary of Broadcom.
The details
The VDDK functions as an interface for reading and writing data within VMDK files, a container format used for virtual machine disks. By restricting this library, Broadcom forces software vendors and administrators to rely on approved partner channels to maintain compatibility. The company stated this shift reflects an enforcement of existing license terms for the development kit.
Timeline
August 25, 2026: Broadcom removed public download pages for the VDDK.
The Tech Race
This move aligns with Broadcom's broader post-acquisition strategy to tighten VMware software licensing and distribution. It forces independent developers into the Technology Alliance Program, marking a departure from the previously open-access model for essential disk management tools.
Software vendors and system administrators who previously relied on the public VDDK downloads must now secure access through the Technology Alliance Program. Those without partner status may face immediate hurdles in updating or developing applications dependent on the VMDK format.
The takeaway
The move formalizes a closed-gate approach for essential virtual disk utilities. Developers should audit their current dependencies on VMDK tools to ensure continued access through authorized channels.
