Custom RSS feeds by topic, keyword or site

Every topic, word and site in the directory can be a feed of its own. Say what you want below, copy the address into any RSS reader, and new posts arrive there as the feeds publish them.

Ready-made RSS feeds and OPML

RSS gives you one feed of a topic's newest posts. OPML is a list of the topic's feeds themselves: import it into a reader and you follow each one from its publisher. Every topic page has both.

Building the address by hand

Add any of these to https://rss.mobi/rss.xml. Filters combine — a post has to pass every one — and several values in one filter, separated by commas, mean any of them. A filter the directory cannot read is left out rather than answered with an error, since a reader app has no way to show one.

tag=ai,robotics
Posts filed under any of these topics — the last part of a topic page's address.
q=open source
Posts whose title or excerpt has every one of these words. Put a phrase in quotes to keep its words together.
exclude=deal,sponsored
Leaves out a post whose title has any of these words — whole words, so “deal” leaves “Ideal” in.
host=theverge.com
Posts from these sites only, by address, without www.
feed=hacker-news
Posts from these feeds only — the last part of a feed page's address.
lang=en
Posts in one language, by its two-letter code.
since=2026-09-01
Posts published on or after this date.
limit=50
How many posts the feed carries: 30 unless you say, 100 at most.

For example, /rss.xml?tag=gaming&lang=en&exclude=deal. The same filters work on the JSON API, and a combined feed keeps a set of them under a name of your own.

What arrives in them

Each post's title, a short excerpt, its picture and a link to the original — the whole post is on the publisher's site. Posts arrive as the directory checks its feeds: within an hour for a feed people read, less often for one nobody has opened in a while.
