hehe mine was up and running way before theirs. but we have diverged quite a bit. might be biased but i think mine is easier to jump right in. mine is more like the draw.io of database editors while theirs is the miro, yk?
LOL I don't know actually, but I will definitely give your project a go when I have to mock up my next DB schemas.
It seems like your project is more grassroots than theirs, so hopefully you can use it to make some money... Not sure how your platform works, but do you provide (paid) storage, syncing, multi-user collaboration, etc.? That seems like the predictable monetization strategy.
