Is there a way to show subreddits as rss feeds?

I tried to add “.rss” as described on many sites talking about this feature on reddit:
How to Get an RSS Feed For Any Subreddit (howtogeek.com)

But when I add a new site in newsblur, I see the ‘progress circle’ going on forever and not adding the site in my list.

That should work. I just tried with two different subreddits and it worked.

More info straight from reddit here https://www.reddit.com/wiki/rss/

If that still doesn’t work, post the actual URL you are trying to add.

There is also: https://reddit-top-rss.herokuapp.com/?subreddit=pics

Which offers a bit more flexibility - especially if you are subbed to high volume subreddits.

I would recommend using the following format to only see ‘top’ posts:

https://www.reddit.com/r/subredditname/top/.rss

e.g. top scoring links : formula1

(note the dot before rss)

Regards.

I don’t think the slash-dot is necessary, this works:
https://www.reddit.com/r/formula1/top.rss

Can also do ‘new’:
https://www.reddit.com/r/formula1/new.rss

or searches:
https://www.reddit.com/r/formula1/search.rss?q=lando&restrict_sr=1&sr_nsfw=&type=link

I use searches on some marketplace type groups- can find a product you’re looking for, or something that is being sold near you.
