Yes, this website is an example of a website built with Sovereign Stack. This Ghost website is based on the Digidocs theme and follows a common Value4Value post format that can be used to monetize an open source software project. The BTCPay Server crowdfunding app and Point of Sale app 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.
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.
