It's similar to BTCPay in that it lets you run software on top of any Bitcoin wallet.

The main difference is that you don't need to run a node to use Zaprite.

BTCPay is awesome, but the vast majority of people are not going to run their own node. Zaprite aims to fill that gap where people can simply connect their own wallet and access a range of financial services, but delivered through a much better UI/UX.
