Minor notes after researching the tools some more:
- Neither tool is free as in freedom. They're proprietary and the limited source code they released is different from the binaries they provide.
- They have not released a Linux version and any port is impossible due to the proprietary nature.
- They only support Nvidia GPUs.
- The WebGlaze tool is invitation only. This isn't in and itself a bad thing, except you can only request an invitation via Instagram or Twitter.
- One or both of the projects have violated the GPL at one point early on.
I'm not an artist but nearly all of the aforementioned points lead me to have a resoundingly negative view of the project. Maybe I'm cynical but it seems they intend to make the tool subscription-based in the future after gaining enough market share.
