The short answer
Reddit is retiring its RSS and Atom feeds. The announcement sets 13 Nov 2026 as the date every feed stops, and Reddit has said there will be no replacement. In the run up, feeds have been intermittently blocked or rate limited for readers and bots, so "my Reddit feed stopped" has usually meant one of four things, listed below. After 13 Nov 2026 it means one thing.
Four reasons a Reddit feed stops
1. Rate limiting. Reddit answers a feed fetch with 429 Too Many Requests when a reader or a shared IP polls too often. Hosted readers that fetch on behalf of thousands of users hit this constantly, which is why a feed can work in one reader and fail in another. The reader shows the feed as erroring or silently stops updating it.
2. Blocked user agents. Reddit blocks requests whose user agent looks like a generic script. Some readers and most RSS bots fall into that bucket, and the response is a 403 or an HTML page where a feed should be. The reader reports a parse error.
3. A private, banned or quarantined community. The feed returns a 403 or an empty list. There is nothing to fix on your side.
4. The feed has been retired. From 13 Nov 2026 every feed on reddit.com returns an error or a redirect to the HTML page. Readers mark it dead. This one is permanent.

# The same feed at Redlisten, with your key in the URL
curl -s "https://api.redlisten.com/r/python/new.rss?key=rl_live_YOUR_KEY" | head -20How to check
Open the feed URL in a browser. If you see XML, the feed is alive and the problem is in the reader or its IP. If you see a Reddit HTML page, a "blocked" message or an error code, the feed is not being served to that request. A curl -I against the URL shows the status code without the page. A 429 clears after a wait; a 403 on a public community usually means the user agent; anything after 13 Nov 2026 means the feed is gone.
The fix that lasts
Redlisten serves the same feed paths in the same Atom layout at api.redlisten.com, with your key in the URL. Take the Reddit feed URL, swap the hostname, append ?key= and your key, and put the new URL in the reader. Read state and folders in the reader stay as they were when the reader lets you edit a URL in place; a reader that cannot edit needs the old feed removed and the new one added.
https://api.redlisten.com/r/{sub}/new.rss?key=for a community's new posts.https://api.redlisten.com/r/{sub}/comments.rss?key=for its new comments.https://api.redlisten.com/r/{a}+{b}/new.rss?key=for several communities in one feed.https://api.redlisten.com/user/{name}.rss?key=for an author.https://api.redlisten.com/search.rss?q=&key=for a search.
The entries carry the same fields Reddit's did, so filtering rules in the reader keep working. Removed posts show [removed] as they did on Reddit. Multireddit and home feeds are not served; a + list replaces them.
Readers, bots and mod tools
A feed reader is the simplest case: edit the URL. An RSS bot in Discord or the RSS app in Slack takes the new URL through its edit or subscribe command. A mod alert built on a comments or search feed takes the same path at the new host, and the comments feed covers every public comment in a community, which Reddit's did not do well. The RSS switch page goes through each case, and the feed readers page covers the moderator setup.
What it costs
A free key is created at signup with 250 requests a month, and each feed fetch is one request, so a feed polled every few hours fits for free. A reader with many feeds, or a short interval, fits a Pro key at $29 a month with 50,000 requests, as listed on 6 Nov 2026. There are no daily caps. If you want the alert rather than the feed, a keyword stream on a paid plan posts matches to Slack or Discord directly, which is the keyword alerts page.
