Nextcloud

 Nextcloud  is an open source software project for self-hosted personal web services including a file manager (an indie version of Dropbox), music, calendar (CalDAV), contacts (CardDAV), and more. It was forked from ownCloud in early June 2016.

Applications
Nextcloud functionality can be added through applications.

Nextcloud News
Nextcloud News provides an RSS aggregator and feed reader. It offers a RESTful API for app developers. Available in the Nextcloud App Store: https://apps.nextcloud.com/apps/news.


 * Might be worth looking into adding mf2 h-feed support to Nextcloud News — assess how much work would it take, would the maintainers support it etc. —

Nextcloud Tasks
Nextcloud Tasks provides task tracking and management, and syncs with popular desktop and mobile task management applications like 2Do.
