Where Does Reeder Store Its Library?
Where Reeder keeps its Realm database and settings in its Mac sandbox, and how the bundle name shifts by version.
Last updated
Reeder keeps its library in a Realm database inside its macOS sandbox container, with settings in a plist beside it. The container name carries the major version, so Reeder 5 paths differ from older releases. Articles sync lightly through iCloud while full content stays local.
Cache bloat is the classic complaint, with image-heavy feeds filling gigabytes under the same container. Clear it from Preferences rather than by deleting folders, since the app prunes database entries when files vanish. Export feeds as OPML before any surgery for a clean restore path.
Where Reeder stores this, by platform
~/Library/Containers/com.reederapp.5.macOS/Data/Library/Application Support/default.realm
Realm database default.realm plus Preferences plist under the versioned container. Bundle ID shifts per major release, so confirm the folder holds a live database. Clear cache from Preferences, never by deleting container folders.
Frequently asked questions
how do I back up Reeder
Copy the Realm database file from the sandbox Application Support folder with the app closed. Settings travel in the Preferences plist beside it. Newer Reeder versions sync through iCloud, so local copies matter most for offline archives.
Reeder uses huge disk space, how to clean
Open Preferences and clear the cache there instead of deleting folders by hand. Hand deletion risks database pruning that drops library entries. The cache can balloon with image-heavy feeds, which is the usual reason to purge.
which Containers folder is the right one
Match the bundle ID to your major version: Reeder 5 uses the .5. variant in Containers. Older releases used different IDs, so check which folder actually holds a fresh database. Copy paths from version-matched guides only.
