what is this software?

I saw a picture, but can’t judge its name. Does anyone recognize it? thanks

The program’s name is Marmoset Hexels 3. It is a grid based vector art, pixel art, design and animation software developed by Marmoset.

Here’s a link if you are interested: https://www.marmoset.co/hexels/

Some kind of isometric voxel thing? Could be a tiled cell editor too, if you can’t rotate the camera.
