This is a free service to convert websites into rss feeds, this only really works on marxists.org type simple websites, not twitter or something like that.
As an example I made an rss feed for https://www.cmpfr.xyz/latest a website feed that @DivineChaos100 among others uses, the rss feed is here https://feed43.com/0560638372445360.xml
You basically just isolate the particular html of where the articles/posts are being posted on the website using {%} to represent things like the links and the titles and use {*} to link different things together, I used
<div class="">{*}<a class="title text-lg transition-opacity hover:opacity-60" target="_blank" rel="noopener" onclick="registerVisit({%})" href="{%}">{%}</a>{*}</div>
and then set what you want the title, link, and, body of the rss posts to be in this case I did {%3} {%2} {%1}
representing the information 3rd 2nd and 1st {%} in the above code
(if you try this and click preview, with wrong information, it might break the feed, so just start over and do it correctly and it should work)
This is a useful and free (to my knowledge, there is no log in required) website for turning more obscure websites that don’t have them into RSS, if you have anything you would want turned into RSS I can give it a shot if it seems easy/ I have the time
