I’m not the owner of the project or even know how to code myself. I do however use it quite frequently with my group when I play so thought I’d try and help out by spreading the word.
If you have any interest in helping out it’ll be greatly appreciated by me and probably many more.
Upvoting because Foundry VTT was an excellent virtual tabletop when I used it for online D&D sessions a year or two ago. (Good features, great extensibility, both managed and self-hosting available, no client app required, no subscription fees.) If I were going to play The Witcher RPG, I would be happy to see it available for Foundry.
