As answered by people managing Codewars and Galerra.art.
Galerra.art's answer:
Galerra started as a passion project by a front-end developer who was frustrated with boring portfolios and static image walls. The idea:
“What if anyone could build a 3D art gallery like in Blender, without needing to code or learn game engines?”
It began as a weekend prototype using React Three Fiber and quickly evolved into a full product. Now it’s a growing platform for creators who want to stand out and own their visual space online.
