With now three device hardware databases for OpenGL, OpenGL ES and Vulkan, I decided to create a single landing page the will display links to those three databases along with the number of uploaded reports.
This is written in PHP just like the databases and the sources can be found at github.
The landing page will direct to the different databases and also displays the number of reports uploaded to those databases.
Combined Android OpenGL ES and Vulkan listing
While the landing page mostly is just a simple link setup, gpuinfo.org also includes a special device listing page for Android at android.gpuinfo.org that combines data from the OpenGL ES and Vulkan database.
Using this you can check what devices support those APIs and quickly get e.g. a listing of android devices that support Vulkan and OpenGL ES.
