https://feed43.com/ : a bit technical but the free version is sufficient for most sites
All other solutions are quite limited in their free version (5 news per day and feed deleted if nothing happens during 1 week)... and quite expensive in their paid version.
FetchRSS
Feedity
Feed Creator
This last one have a inexpensive "to host" version.
An RSS link on homepage AND a RSS Autodiscovery link in the source code is for me the best solution. RSS Autodiscovery make it discoverable by any RSS reader
Looking at the blogroll he's talking aboit, I counted :
9 blogs with RSS Autodiscovery + link pointing to the RSS feed
20 blogs with RSS Autodiscovery only
3 blogs with link to the RSS feed
4 blogs with nothing (including it's own blog)
RSS link+autodiscovery would be so cool on every blog!
There's plenty of really good solutions around :
1. Online: Inoreader, Feedly, Newsblur Newsbin, The Old Reader, Feeder...
2. Browser extension: the great Feedbro
3. Desktop: Liferea (Linux), QuiteRSS (Windows), Caffeinated, Readki, Reeder (MacOS)
For RSSOwl and RSS Bandit (Windows), there's nothing new for years/
The great FeedDemon (Windows) stopped it's dev years ago.
3. Self-hosted: Tiny Tiny RSS, Fever, Leed, Selfoss
Totally agree! Subtome was a great project but it lack updates. I talked weeks ago with @julien51, it's creator, and he told me that it didn't have time maintaining it but he would integer contributions.
I discuss it with one dev contributor of Mozilla and they say that they didn't want to loose time maintaining Live Bookmarks. And the Live Bookmarks was underused. RSS is no more a prioritary subject.
The problem is that they don't only suppress Live Bookmarks, they suppress all the ability to manage (I mean detect and display) RSS feeds... and that's terrible!
Awesome RSS is a great extension, and is compatible again with Firefox 64+ and now adds direct subscription feature to Feedly, Inoreader, NextCloud Reader and even Tiny Tiny RSS (or universal feed display.

Another great new extension is Want My RSS because it's compatible with 10 RSS readers for direct subscribtion (you can add your own when you have a self-hosted reader for example). Feed detection and feed display is also great!
