Substack RSS Feed Finder
Every Substack publishes an RSS feed, but nothing on the page tells you where it is. Paste the publication URL, a link to one post, or a custom domain, and this tool derives the feed address and verifies it is live — item count, publication title, and latest post. Then copy it into Feedly, Inoreader, NetNewsWire, Blogger, WordPress, or a Zapier trigger.

Public feed vs private feed
Two different feeds exist for every paid Substack, and mixing them up is the usual reason a reader shows previews instead of full posts.
| Public /feed | Private subscriber feed | |
|---|---|---|
| How you get it | Derived from the URL — this tool | Issued by the Substack app to your account |
| Contains | Free posts, plus previews of paid ones | Full paid posts you subscribe to |
| Safe to share | Yes — it is public | No — it is effectively a password |
| Works if you cancel | Yes | No — the token stops returning paid posts |
- Feeds carry roughly the latest 20 posts, not the whole archive — use the /archive page for older material.
- This tool never asks for the private feed, and you should not paste it into any third-party service you do not control.
How to find a Substack RSS feed URL
- Paste any Substack link. The home page, the archive, a single post URL, a bare subdomain like name.substack.com, or a publication on its own custom domain — all of them work.
- Let it derive the feed address. Every Substack serves its feed at /feed on the publication origin. The tool strips the post path and rebuilds that address for you.
- Check that the feed is live. Press Check feed. The result shows the publication title, how many posts the feed carries, and the most recent one — so you know you have the right publication before wiring it up.
- Copy it where you need it. Paste the URL into any reader or automation that accepts a feed. For paid posts you need your private feed instead, which the Substack app issues to your account.
Frequently Asked Questions
- What is the RSS URL for a Substack?
- It is the publication origin followed by /feed — for example https://example.substack.com/feed. Publications on a custom domain use the same pattern on their own hostname. Substack does not link to it from the page, which is why it is hard to find, but it is always there for public posts.
- Does this work for Substacks on a custom domain?
- Yes. A publication that moved to its own domain still serves /feed on that domain. If the live check fails on a custom domain, the site may not be a Substack at all — try /rss or /feed.xml, which are the common patterns on Ghost and WordPress.
- Where do I find my private RSS link in the Substack app?
- Open the publication in the Substack app, open its menu, and choose the RSS / "Add to podcast app" option. The link it gives you contains a token unique to your account, which is how paid posts reach your reader. It is not derivable from a URL, and you should treat it like a password — anyone who has it can read your paid subscription.
- Why does the public feed not include paid posts?
- Paywalled posts are excluded from the public feed by design. The public /feed carries free posts and the preview portion of paid ones. Full paid content only flows through the personal feed tied to your subscription.
- Do you store the URLs I check?
- No. The check fetches the public feed once from our server and returns a summary. Nothing is written down. The server-side step exists only because Substack does not send CORS headers, so a browser cannot read the feed directly from this page.
- How many posts does a Substack feed contain?
- Typically the most recent 20 or so, not the full archive — the live check shows the exact count for the publication you entered. For older posts, use the archive page rather than the feed.
