Turning Your Bookmarks Into an RSS Feed You Can Read Anywhere

I still read most things in NetNewsWire. Not X, not Bluesky, not whatever app happens to be open on my phone that day, a feed reader. So once Birdfeeder had a searchable archive of everything I'd bookmarked, the obvious next step for me personally was making that archive show up in the one place I actually read things.

Every account gets a private feed URL from Settings, and it comes in two flavors: an Atom feed and a JSON Feed. I built both because I didn't want to bet on one format outliving the other, and JSON Feed clients have gotten genuinely decent even if Atom is still the safer default for older readers. Each entry carries the full post text, mentions and hashtags intact, any photos inline, and a link back to the original post if you want to jump to the source.

The feed URL is tied to your account and meant to stay private. If it ever leaks, there's a regenerate button in Settings. One click and the old URL stops working immediately.

This feature didn't need anything new from the bookmark data itself. The feed is just another view over the same archive that full-text search and the weekly digest already read from. Once the underlying data model treats a bookmark from X the same as one from Bluesky or Mastodon, adding an RSS wrapper on top is a small addition rather than a new subsystem.
