Here's a 3rd option :)

For RSS/Atom feeds presented as links in a site (for convenience to users), developers can always offer a simple preview for the feed output using: https://feedreader.xyz/

Just URL-encode the feed like so: https://feedreader.xyz/?url=https%3A%2F%2Fwww.theverge.com%2...

...and you get a nice preview that's human readable.
