feed readers

• Tiny Tiny RSS, this is what I've been using for years. Android app(s) on F-Droid, and there's at least one iOS app.
• Miniflux
• Vienna RSS
• FeedReader, a desktop client.
• Fresh RSS
• RSS Guard desktop RSS reader for Linux, BSD, OS/2, macOS, or Windows that supports RSS/ATOM/JSON/iCalendar/Sitemap feeds and also web-based services such as Feedly, Nextcloud News and TinyTinyRSS.
• Winds
• Stringer
• Selfoss
• feedbin
• Leed
• commafeed
• Feedbro is a feature-rich browser plugin feed reader, but it's not open source, so not recommended.

Note: this list is not exhaustive. If you know of a feed reader I've missed, let me know and I'll add it.

tools that make it easier to add sources to your feed reader

• FiveFilters
• https://rssgizmos.com (including feed freshness checker, OPML maker, and OPML peeler).
• Feedsearch, an API service for searching websites for their RSS, Atom or JSON feeds.
• GetRSSFeed. Shows RSS feed URL for Soundcloud or Apple "podcasts".
• FetchRSS. Works well for those Soundcloud "podcasts", but this site requires registration (which suggests that this site is creating their own feed endpoint instead of simply exposing soundcloud's already existing (but well-hidden) RSS endpoint).
• rss discovery engine, pre-alpha, by Brandon Quakkelaar (via Rubenerd)
• https://feedle.world a search engine for blogs and podcasts
• Explore RSS feeds in your own neighbourhood (interesting project)

Is the podcast you want to listen to hosted on Soundcloud? First of all, double-check that the podcast is not also hosted somewhere else (more often than not that is the case, and then you can simply avoid Soundcloud).
Soundcloud makes it really hard to discover the podcast's RSS feed. It is not shown anywhere on the page, nor in the HTML source.
Based on a feed URL we already possess and that channel's Soundcloud landing page, I think the following method is necessary to manually construct the hidden RSS feed endpoint for any Soundcloud "podcast":

1. Open the HTML source of the Soundcloud "podcast", for example https://soundcloud.com/user-268302561.
2. In the HTML source, find the user ID property, which looks like this soundcloud://users:819898639 (I suggest search for soundcloud://users).
3. Copy the numeric part, and construct a URL like this: https://feeds.soundcloud.com/users/soundcloud:users:819898639/sounds.rss.
   Take a moment to reflect on the awfulness of siloed web services and do your best to avoid encouraging them in future.

Cloudflare is user-hostile and site owners using it should beware

I occasionally encounter feeds that my feed reader cannot subscribe to because the site uses Cloudflare DDoS protection, which Cloudflare implements in a manner contrary to the ethics of the open web, in the process making it near impossible for feed readers or read-it-later services to access the content.

I have no simple work-around for such RSS feeds - they are effectively rendered useless by Cloudflare's discriminatory and user-hostile blocking
implementation.

Cloudflare themselves claim doing nothing wrong, and that it is in fact the site operators that have misconfigured their Cloudflare firewall and that users should contact the site operator. Which is simply ridiculous.
If Cloudflare cared at all about the open web, this issue would not be relegated to a few obscure forum posts. They could also easily implement some form of automatic exemption from their page blocking for common feed endpoints, such as /feed, rss.xml and similar.
