Bort does just that, uses browser's IndexedDB and syncs via Dropbox.

Works well for something smaller, like what people commonly have as browser bookmarks. https://bort.io/ https://bort.io/ Some comparison on the about page against other services: https://bort.io/about.html https://bort.io/about.html
