I've been running it for years and heartily recommend it. Both the web and android clients are very robust. The killer feature for me is the ability to share arbitrary content to your own public feed provided by the ttrss instance. (https://tt-rss.org/gitlab/fox/tt-rss/wikis/ShareAnything)

I'd recommend using Postgres as opposed to Mysql, as that is what author specifically recommends (mysql support has been a bit subpar)
