How it works

RSS and Atom entries map to a common title, link, date, summary, and identifier model, then sort by publication or updated time and deduplicate by stable ID or canonical link. Source labels remain attached.

  • Newest-first matches feed readers.
  • ID and link deduplication prevents syndicated repeats.

Worked example

Merge two blog feeds
Combine entries from two JSON feeds and deduplicate by entry ID
Input
											Input1: {"title":"Blog A","items":[{"title":"Post 1","id":"1"}]}
Input2: {"title":"Blog B","items":[{"title":"Post 2","id":"2"}]}
Output
												{
  "title": "Blog A + Blog B",
  "mergedAt": "2026-08-25T12:45:14.753Z",
  "totalEntries": 2,
  "entries": [
    {
      "title": "Post 1",
      "id": "1"
    },
    {
      "title": "Post 2",
      "id": "2"
    }
  ]
}

When to use this

Personal readers, newsroom monitors, and release dashboards merge feeds.

Edge cases

  • An entry without GUID or id needs a canonical-link fallback.
  • Atom updated time can differ from original published time.
  • A reused URL may represent revisions and need date-aware handling.
