What is an RSS feed? A plain-English guide

An RSS feed is a structured list of a website's newest items — titles, links, dates, and short descriptions — written in a format software can read. Instead of visiting ten websites and scanning for what changed, you subscribe once and let a reader or bot deliver only the new items.

Why RSS still matters

RSS never went away; it moved into the background. Podcast apps use it. Newsrooms still publish it. Automation tools and AI agents prefer it because a feed is clean data rather than an ad-heavy page.

The core promise is still the same: you choose the sources, and you get updates without an algorithm deciding what you see. No notifications from a platform, no ranking, no infinite scroll. Just the items, in order.

How an RSS feed is structured

A feed is XML with a channel and a list of items. Simplified, it looks like this:

<rss version="2.0">
  <channel>
    <title>Example Feed</title>
    <link>https://example.com</link>
    <item>
      <title>New article title</title>
      <link>https://example.com/article</link>
      <pubDate>Mon, 19 Oct 2026 08:00:00 GMT</pubDate>
      <description>A short summary.</description>
    </item>
  </channel>
</rss>

Every feed reader understands those fields. That is why a single feed works in a desktop reader, a phone app, an email digest tool, and a chat bot at the same time.

What you can do with a feed

• Read it in an RSS reader or a feed-to-email service.
• Route it into Slack, Discord, or Telegram so a team sees updates where it already works.
• Automate it with rules like "email me a digest every morning" or "post to this webhook when a new item appears."
• Analyze it in a spreadsheet, a database, or an AI pipeline.

The format is old, boring, and reliable — which is exactly why it is useful.

The problem: most sites do not publish RSS

Plenty of valuable pages have no feed at all: a company's news page, a government notice board, a niche blog, a category listing, a search result. If a page is public, though, it can usually be turned into a feed by reading the page and extracting the repeating items.

That is what RSSFlux does. You paste a URL, and it either finds the site's existing feed or scrapes the page into a new one — with titles, links, dates, and thumbnails. You can then read that feed anywhere, or route it to Slack, Discord, Telegram, email, webhooks, and the API.

RSS versus "just check the site"

Checking a site manually works until you have more than a handful of sources. RSS gives you:

1. A single inbox instead of ten browser tabs.
2. Only new items, so you stop re-reading the same page.
3. A stable format that tools can automate.
4. Ownership — the feed is yours; no platform decides what you see.

How to get started

1. Pick a source you check regularly.
2. See whether it already offers an RSS link.
3. If it does not, create a feed from the URL with RSSFlux.
4. Add the feed to your reader — or connect a bot so it lands in chat.
5. Upgrade only when you need more feeds or faster refreshes; the free plan includes three feeds.
