Selfoss is a personal RSS feed reader written in PHP. The idea is that you install it into a subdirectory of your website or on your laptop, configure it, and use it to read RSS feeds in the same way that you'd use Google Reader (RIP). Can be easily extended with plugins. Supports mobile devices as well as desktop web browsers. Can also import existing OPML feeds (like Google Reader's) to populate the database with what you read. Tiny - 2MB in size.
