I hope it will be compatible with FreshRSS  
https://github.com/FreshRSS/FreshRSS 
FeedMe is a good example to build upon, using their stable version personally

FreshRSS is explicitly mentioned on https://github.com/martinrotter/rssguard. I therefore assume that there should be no problems.
Sorry, didn't check the GitHub.  
There's a pattern of users sharing early builds of their software, I was jumping to a conclusion. 
Android user too.
can anyone explain the reason of this error ? i cant seem to follow this feed https://lemmy.ml/feeds/u/inasaba.xml?sort=New

thx
To test the RSS implementation & find if a domain has one:
Temporary workaround to view the RSS feed before adding it to your aggregator
This has nothing to do with RSS Guard. The link does not work in general. Https://lemmy.ml/feeds/u/dessalines.xml?sort=New, for example, does work. There seems to be something wrong with lemmy.ml. The administrators have to take care of that.
ty for clarifying
