Backfeed—an unforgettable feed processor

Backfeed takes an RSS feed and concatenates it with deduplicated historical items from the feed saved in the Wayback Machine. You’ll get a Backfeed URL to enter into your news aggregator or podcatcher which will give you access to a larger set of items than the official feed. This is useful when a RSS feed author includes only a few items in the latest feed, but you know there are older items which are just not listed. Using Backfeed you can access the maximum available feed content.


  1. Request a backfeed access key (from me, at ). Enter it into the access key field above.
  2. Find the URL to an RSS or podcast feed. Enter it into the Feed URL field above.
  3. Click Backfeed it!
  4. Wait a minute for it to process.
  5. The new feed URL will be printed on your screen.
  6. Copy this new URL into your feed reader.


What kind of RSS feeds can Backfeed process?
Backfeed can process any XML-formatted RSS feed, for both podcasts and articles.
Are all back items retrieved?
Sometimes, it depends. Backfeed will retrieve up to 5000 unique snapshots from Usually that means much more than 5000 individual items, if that many are archived for the feed. If a feed is updated frequently, and has a very large history, 5000 snapshots may not be enough to include the full history.
Some podcast episodes are missing!
For feeds with linked media (such as podcasts) the existence of each file is confirmed. Episodes with missing media files (not uncommon for very old episodes) will be excluded from the Backfeed output.
Is Backfeed bulletproof?
Probably not! Backfeed is not mature software, and probably doesn't work with all URLs. If a Backfeed-generated URL works for you, it will continue to work as long as: a) the original feed URL does not change, b) continues to hold historical content for that URL, and c) Backfeed continues to operate as a service.
What else can go wrong?
Is this a free service?
Free for now, but bandwidth costs have forced me to limit the number of people with access to the service. If you like Backfeed, saying thanks with cash will help encourage me to keep the service online. ;)
