Host an Atom feed and share the URL
Put an Atom feed at a public address that readers can subscribe to — the stricter, better-specified sibling of RSS.

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your ATOM file is live at your-name.99helpers.site in about ten seconds.
What is a .atom file?
Atom is an IETF-standardised syndication format created to fix RSS's ambiguities — it mandates ISO 8601 dates, requires unique IDs, and specifies content handling precisely. Technically better; less universally recognised by name.
What people use ATOM files for
- Feeds for blogs and documentation sites
- Release notifications from code hosting
- Content syndication
- Feeds generated by static site generators
What opens a ATOM file
- Every feed reader
- Any browser, which displays the XML
- GitHub and GitLab, which publish Atom feeds
- Automation tools
How to host a ATOM file
- 1
Drop your ATOM file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
- 2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: atom-feed.99helpers.site
- 3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
Browsers show the XML tree; readers subscribe to the address and poll it.
Why host a ATOM file instead of emailing it?
A static site's feed needs a URL and nothing more. Hosting it avoids standing up a server for one XML file.
Worth knowing before you publish
- Atom requires ISO 8601 dates, unlike RSS's RFC 822 — a common source of invalid feeds.
- Every entry needs a unique, stable id element.
- Validate before publishing; readers reject malformed feeds silently.
ATOM hosting questions
- Atom or RSS?
- Atom is more strictly specified and less ambiguous. RSS is more widely recognised by name. Every modern reader supports both, so it's largely a matter of what your generator produces.
- Will readers pick up updates?
- Yes, on their own polling schedule — typically anywhere from minutes to hours after you republish.
- Is it served with the right content type?
- Yes, application/atom+xml, which is what feed readers expect.
