Several sites, including Tumblr and Craigslist, have removed their RSS feeds. Other services, like TikTok, never offered an RSS feeds to begin with. This is annoying if you want to follow things without creating an account, the way you can with Bluesky and Mastodon. Even worse: there are even some news sites that don't offer feeds, which is a problem if you're setting up an RSS reader and hoping to follow your favorite sites.
OpenRSS is a free service that builds open RSS feeds for various sites. Unlike similar services, this isn't automated—the team there actively builds and maintains the integrations. The service is run by a nonprofit that is transparent about its financials right on the about page.
You can head to their feeds page to see an overview of apps that are supported—click any of them to find more details about how to use it. For example, for Craigslist, you can browse the site to any region then either run a search or head to a sub-section. In your browser's address bar, add openrss.org to the beginning of a domain in your address bar. Hit enter and an RSS feed for the page will open. This means you can keep track of anything you're hoping to buy—just create an RSS for the term and you'll see when someone posts it.
Tumblr works the same way: head to any profile page and add openrss.org to the beginning of the URL, as in openrss.org/www.tumblr.com/username. You'll now get every new post by that user right in your feed reader.
OpenRSS offers feeds for more than the apps listed on their feeds page. You can find others by adding the URL openrss.org to the beginning of any website on the web—if OpenRSS offers a feed for the site, it gives it to you (and if not, you'll see a page explaining that). It's a quick way to find feeds for sites that don't make them obvious. Keep OpenRSS in mind the next time you can't find an RSS feed—it just might do the trick.
