We’ve made changes to our tooling to gather and display software icons on awesome-selfhosted.net.
There are a few layout changes that should come “soon” when time allows (too much whitespace, not enough info displayed at once, there has to be a middle ground between the current HTML version and the extremely packed markdown version… there are a few ideas lying around in the issue tracker).
