selfoss – A Flexible & Open Source RSS Reader/Aggregator
selfoss is an open source and lightweight web application that can fetch content from any number of sources.
RSS is the content type supported by default, however, with its plugin system, any new source types (log files, e-mails, etc.) can be implemented by adding a single class.
The application has a simple-yet-functional interface which also supports navigating via keyboard.
It is also flexible in means of the database used; you can either go with MySQL, SQLite or MongoDB.
