moonmoon 
Moonmoon is a web based aggregator similar to planetplanet. It can be used to blend articles from different blogs with same interests into a single page.
Moonmoon is simple: it only aggregates feeds and spits them out in one single page. It does not archive articles, it does not do comments nor votes.
Requirements
You will need a web hosting with at least PHP 5.6 (PHP 7 is also supported).
If you are installing moonmoon on a Linux private server (VPS, dedicated host),
please note that you will need to install the package php-xml.
Installing
Installation steps (shared hosting or virtual / dedicated server) can be found in the wiki.
Docker images are also available in moonmoon/docker-images. Theses images are probably not production-ready but should work for manual testing.
