Where Does Stack Browser Store Profile Data?
Stack Browser keeps spaces, cards, and profiles in a Chromium-style user data folder. How to confirm the exact path is inside.
Last updated
Stack Browser is built on Chromium, so it follows the Chromium layout: one user data directory holding history, bookmarks, cookies, and per-profile subfolders like Default. Spaces and card state live inside those profiles.
The folder name can shift between releases, so treat the version page as ground truth. Open the version page, copy the Profile Path, and back up its parent folder with the browser closed. Spaces map onto profiles, so one backup covers every workspace.
Where Stack Browser stores this, by platform
%LOCALAPPDATA%\Stack\User Data
Chromium-style user data root; profiles sit in subfolders such as Default. Confirm via stack://version Profile Path, since the vendor folder name can change between releases.
~/Library/Application Support/Stack
Same Chromium layout as Windows. If the Stack folder is absent, check the version page first: custom installs sometimes rename the vendor directory.
Frequently asked questions
How do I find my exact Stack profile path?
Type stack://version or chrome://version in the address bar and read the Profile Path field. Its parent folder is the user data directory you should back up.
How do I back up Stack spaces and profiles?
Quit Stack completely, then copy the whole User Data folder to external storage. Restore it to the same location on the new machine before launching.
