If you create native AR apps and use Unity, this is a great tool that can speed up the creation process and help you in debugging. AR Foundation Editor Remote is a plugin made by Kyrylo Kuzyk. My personal opinion is that it is worth 10x more than Unity MARS but costs much much much less. No matter if you are pro or coding beginner - this asset is essential for programmers.

I am not related to the original creator of the asset or Unity’s officials and I haven’t written a sponsored post. I am just yet another happy customer, there is no money involved.
