I run Linux + Android on my devices so can't check out Reeder unfortunately. However, my setup works fine:
- RSS: FreshRSS hosted on personal server, use web interface on desktop and the truly awesome FeedMe on mobile
- Reading: Wallabag hosted on personal server, use web interface on desktop and the Wallabag app on mobile
- Bookmarks: Shaarli hosted on personal server, use web interface on desktop. I can share articles on mobile via Shaarlier but not consult them - but I don't feel the need to; I use it as a "check this website later" thing where I delete the entry after checking or storing it in my org-mode setup if I want to keep it.
Reader would replace pretty much all of that, which is nice. But it comes at the cost of 1. monthly subscription, 2. not truly owning my data/product and 3. storing all my info on an external server which I am actively trying to avoid with the above setup.
Wallabag is more of an "article saving" app than a bookmarker. Via the web browser plugin it extracts the text and images from a website if it detects an "article" and stores that on your instance. You can annotate, catalogue etc. the articles at will then.
For bookmarking I use Shaarli. The two have a clearly different intended use. Probably Archivebox is combining the two, but that clones the entire HTML of a page which is also not what I was looking for.
For a front end, I use “Reeder 5” - writing this reply in it now. ( https://www.reederapp.com/ )
Couple it with an on demand vpn like Wireguard and I can sync with the freshrss feed at home from anywhere.
And the price was “pay once” not every month.
