Personnaly, I have built a "self-hosted" stack around the following services: * Seafile (file hosting/synchronization/sharing/history) * SoGo (a webmail that work with existing IMAP and SMTP servers and exposes an Exchange API) * Matrix / Riot (matrix is a chat server, Riot is the web client) * Jenkins 2 (Continuous Integration / Continuous Deployment) * FreshRSS (RSS aggregator) Authentication is managed by a single LDAP service (openldap). I also plan to test/deploy: * Peertube (video hosting) * Mastodon (micro-blogging) My next goal would be to distribute this stack on more than one server, in order to improve availability.
