I personally use wanderers guide. It's easy to use and has everything from classes and ancestries to a full bestiary I think.

The only problem is that you are capped at 6 characters max, and the only way to get unlimited slots is to pay for the creators Patreon. In the end for running a first/begginers campaign it's more than enough IMO but if you're using it a lot(like I am) it might be worth it to pay
