SupporterHQ

SupporterHQ was a service that helps open source projects to receive donations. Using Supporter maintainers of open source projects and authors of free content could set-up project pages to accept recurring and one-time payments via PayPal. Additionally, Supporter offered badges users could put into their Github pages or elsewhere on the web. Supporter also allowed to create personal donation pages, not related to any project. A browser extension was available to help users discover content creators on popular web sites such as GitHub or StackOverflow. The service has been shut down on 01.01.2018. Thanks to everyone who has been using it!
