FreshRSS is a self-hosted RSS feed aggregator such as Leed or Kriss Feed. It is at the same time lightweight, easy to work with, powerful and customizable. It is a multi-user application with an anonymous reading mode. It supports custom tags, and PubSubHubbub for instant notifications from compatible Web sites. There is an API for (mobile) clients, and a Command-Line Interface. Finally, it supports extensions for further tuning.
Automate the exchanges of the data between the applications and services you use on the web. Make Twitter talk to Mastodon, make Github talk to Mattermost, store your favorite tweets by creating notes in Evernote, follow RSS feeds and post each news in Wallabag, Pocket or Evernote. The possibilities are too numerous to name all of them, but with that project you won't have to raise your little finger at all: automate everything and make your life easier.
