Ask HN: What's your favorite self-hosted application?

Previously Nextcloud [1], currently bewCloud [2]. Full disclosure: I created bewCloud as a simpler, faster, and modern alternative to Nextcloud.

They've mainly allowed me to get my Files (including Photos), Calendars, and Contacts off of Big Tech. I couldn't live without the RSS and Expenses apps, though.
