A feed-native corner of the web

kbcafe.com has been a developer resource since the early RSS era — when feeds were how the web's writing actually moved around. That heritage is why the Feeds section exists: it is the most on-topic part of the site's history, and it is being rebuilt with modern, no-tracking tooling rather than left to rot.

The pieces of a feed

  • RSS 2.0 — the classic <channel> / <item> format most blogs still publish.
  • Atom — the IETF-standard alternative (<feed> / <entry>), stricter and namespaced.
  • OPML — the outline format used to import and export whole lists of feed subscriptions between readers.

Why client-side

A feed often contains URLs, tokens in query strings, or content you would rather not hand to a third-party service. KB Cafe's feed tools parse everything locally in your browser, so a feed you paste here never leaves your machine — and the tools keep working offline once the page has loaded.

On the way

The validator, OPML converter, RSS-to-JSON, and feed preview tools are being built in the order above. In the meantime, browse the full menu of tools — including the JSON → TypeScript converter, which pairs well with the coming RSS-to-JSON output.
