What Is RSS?

What Does RSS Mean?

RSS stands for "Really Simple Syndication." Depending on which era of the web you first encountered it, you might also see it explained as "Rich Site Summary" — both names have circulated since the format's early-2000s origins, and both describe the same thing: a standard file format, written in XML, that a website publishes so its content can be read automatically by other software instead of only by a human clicking through a browser.

The "syndication" part is the important word. A newspaper syndicates a column to run in multiple papers at once; RSS syndicates a site's posts so multiple readers, apps and services can pick them up without the publisher having to send anything to anyone individually. The feed just sits at a predictable address, quietly updated every time something new is published.

Where the idea came from

RSS grew out of the same late-1990s push that produced RDF Site Summary and Atom — competing but closely related formats solving the same problem: how does a piece of software know a page has new content without a human checking it? RSS 2.0, published in 2002, became the version that stuck, and it's still the format most feeds use today, more than two decades later.

How Does an RSS Feed Work?

Under the hood, an RSS feed is just a text file at a URL — often something likeexample.com/feedor example.com/rss.xml — listing the site's most recent items. Each item in that list carries a handful of standard fields: a title, a link back to the full article, a short description or excerpt, and a publish date. Most blogging and publishing software generates this file automatically, so writing and publishing a normal post is the only action anyone has to take — the feed updates itself.

An RSS reader — an app like Feedporter — does the other half of the work. You give it a site's feed address (or just its normal homepage, and the reader finds the feed for you). On a schedule, the reader fetches that file, compares it against what it fetched last time, and shows you whatever's new. There's no push notification infrastructure involved and no account the publisher needs to know about — the reader is simply checking a public file, the same way any browser would.

A feed and a podcast are the same idea

If you've ever subscribed to a podcast, you've already used RSS without necessarily knowing it. A podcast feed is an ordinary RSS feed where each item also carries an audio file attachment. Every podcast app, regardless of brand, is a specialized RSS reader — proof that the format has scaled from personal blogs to a medium with hundreds of millions of monthly listeners without needing to change.

Why You Should Use an RSS Feed Today

The web most people read today is mediated by algorithms: a social platform's timeline, a search engine's news tab, a recommendation model deciding what you'll probably want to see next. RSS is the alternative that was never replaced, just crowded out — a feed shows you exactly, and only, what the sites you chose actually published, in the order they published it.

That has three practical consequences. First, you see everything from a source you follow — nothing gets quietly de-prioritized because an algorithm decided it wouldn't perform well. Second, you can aggregate dozens or hundreds of sources — blogs, newsrooms, documentation changelogs, a company's release notes — into one reading list instead of checking each site individually or hoping a social post surfaces it. Third, a feed reader has no reason to sell your attention: there's no ad auction happening between you and the content, because there's no engagement metric a feed reader is trying to optimize.

A good RSS app makes the format even more useful than the plain feed file: folders to organize dozens of sources by topic, search across everything you follow at once, and — in Feedporter's case — the ability to track a keyword or search term as if it were a feed of its own, so you're not limited to sources you already know to follow.
