Deep dive into finding RSS feeds

Lighthouse has developed a tool called the Lighthouse Feed Finder to assist users in locating RSS feeds for various websites. The tool employs multiple methods to identify RSS feeds, acknowledging that while many websites do not openly advertise their feeds, they often include metadata that can be detected. The RSS icon is a common way to link to feeds, but many sites do not utilize it. The Feed Finder uses RSS autodiscovery, which relies on specific metadata tags in the HTML of a website, to locate feeds automatically. However, if this method fails, the tool employs advanced techniques such as checking parent URLs, blog sections, sitemaps, and visible links on the site. It also attempts to guess common feed URLs based on standard suffixes. In cases where a website does not provide its own RSS feed, the tool can check third-party services that generate feeds. The Feed Finder aims to improve its capabilities over time and encourages user feedback to enhance its functionality.

- Lighthouse Feed Finder helps locate RSS feeds for websites that may not openly display them.

- The tool uses various methods, including metadata detection and URL guessing, to find feeds.

- It prioritizes finding feeds published directly by websites before checking third-party services.

- User feedback is encouraged to improve the tool's effectiveness in finding RSS feeds.

- The tool is designed to avoid overwhelming websites with requests, implementing caching to manage access.

Back when I was young, websites had this icon you could click that would take you straight to their RSS feed. You young whipper snappers have gone an fucked that up. Actually, I think it was Google's fault. When they killed their RSS reader people pronounced RSS dead so people just stopped publishing RSS feeds or just didn't link to them.

* Yes, I know the article talks about the RSS icon, i'm just soapboxing.

I thank WordPress for most of my RSS feed.

I follow mostly RSS on non technology website, for instance road cycling. people that wouldn't care or know about RSS because they are not very techy, yet because they are normies that use WordPress for all their website it puts a page with RSS feed automatically. You got to find it with developer tool by searching RSS but 99% of the time if it's WordPress it got RSS.

Thank you WordPress you bloated piece of shit :)

I generally try: /rss, /feed, /index.xml, /rss.xml, /feed.xml, etc. And at various root or /directory/* locations. https://blog.jim-nielsen.com/2021/feed-urls/ is a good article with statistics on naming.

I've been adding to my feeds.opml since reddit started dying in ~2015 and now I'm up to around ~1700 feeds and mostly independent from aggregators; though I still collect new feeds from HN/IRC/etc. Mostly I just always make a point to look for them whenever I read something cool on the web.

My modus operandi for finding a non-obvious RSS feed is to check the Wayback Machine's list of saved URLs and search for "RSS", "feed", or "XML". That normally will find the feed as long as it exists.

Tried out the feed finder on my blog again and I have another bug to report - it seems the URLs on the page can cause a crash within the web app! my blog (at matthew.science) uses Zola SSG, and it seems the URLs are formatted with a preceding //: '<a href="//matthew.science/posts/riscv/">Basics of the RISC-V ISA</a>'

This causes the following error: TypeError: URL constructor: //matthew.science/posts/riscv/ is not a valid URL.

This looks very useful. It would work well with Hoarder (would be cool if they were integrated ;)

Note: Hoarder can automatically hoard RSS feeds as part of its 'bookmark everything' functionality. Hoarder uses AI to tag all the content (URLs, feeds, images, notes) so you can then do full text searches on your personal archive of your bookmarks etc.

Its interesting to contemplate an RSS-first browser that would have this functionality built-in. Think for example of promoting to full browser status a desktop RSS reader like Akregator [1] (which already embeds a webview).

The browser as we now know it is mostly a static application that has long lost its user-centric mission. Websites might push some stuff but the user must do thinks manually. Its primary function is to provide a search window to external search. People even stopped using bookmarks and search for everything.

This hypothetical RSS-Browser could become the main organizational tool for the users web experience, integrating the use of bookmarks.

In fact even more "feeds" could be integrated like email and activitypub or atproto posts. It boils down to the fact that each person has a number of profiles/roles and within each they have a taxonomy of interests and we need a tool that integrates static and dynamic sources of information.

This is useful, I set up RSS on my website yesterday.

Turns out the feed finder couldn't find the feeds even though I've linked to them using clickable RSS icons.

I didn't know about the autodiscovery feature so I'll add that now.

I created a lightweight shell script to check many url combinations on a site for feeds.

https://github.com/begriffs/findrss

The combinations came from what I observed in the big list of blogs I follow. The script works pretty well for most sites.

I went canvassing for RSS feeds only yesterday! Some good stuff in here: https://bsky.app/profile/csswizardry.com/post/3lckq4qo6zs22

It’d be neat for readers to seamlessly integrate with a scraper, either self-hosted or commercial, if no feed is found. I believe Inoreader allows scraping a few sites depending on the plan level; most reader services don’t.

I open-sourced pyGoogleNews and wrote a quick blog about how you can reverse engineer google news RSS to turn it into an RSS feed of any website that is supported by Google News

I use a Chrome extension (https://chromewebstore.google.com/detail/get-rss-feed-url/kf...) and it seems to pick out the RSS URLs fairly consistently

I fought this problem, since I wrote my own RSS reader in python. Might not be perfect.

The problem with the approach presented here is speed. Most of the web pages, especially smaller are really slow.

Crawling most of the web pages is pain, especially if you use selenium and small SBC.

Therefore either the page presents a clean nice RSS link, or get lost.

Most of the good, modern pages give you nice RSS. Even GitHub gives you RSS for commits.

For other pages I try openRSS.

For YouTube I use yt-dlp to obtain channel id, to establish RSS.

Algorithm is crude, but gets the job done.

It would be nice if someone ran this on commoncrawl and published a list of all the RSS feeds. (probably someone has?)

Or I suppose you could just find all "Content-type: application/rss+xml" in CC.

I know in the past, when I was looking for large lists of RSS feeds, I didn't really find what I was looking for.

You can add '/display-feed.rss' to the list of common suffixes for many .eu sites

Pasting a URL in NewsBlur also uses several of these techniques to find the feed(s), and it is open source, so the feed-finding code could be ripped out of NewsBlur as an alternative to this.

I would like to be able put multiple websites, I had to build a script based on "Guessing the feed URL" approach to get the rss feeed of a bunch of websites that I had bookmarked

Does it correctly ignore the “Comments on:” feeds that are sometimes mistakenly chosen over the main feed?
