Yes, this website is an example of a website built with Sovereign Stack. It follows a common Value4Value post format that you can use to monetize an open source software project. The BTCPay Server crowdfunding app and Point of Sale apps are used for donation workflows.
The goal of the software project is to lower the barriers to entry for hosting bitcoin-native website infrastructure. The purpose of the website is to host the documentation and the git repo, all of which is accessible to the general public.
The website is a work-in-progress, so expect certain sections to be incomplete or out of place!
A lot of effort has gone into the development of this software. If you appreciate the goals of this project, consider leaving a tip. All donations are applied to the monthly crowdfund.
