The latest version of my invoicing app lets the user install CouchDB on their desktop PC and they can choose to use their local CouchDB only. This "local-first" approach runs offline only and provides close to native app performance. They can also choose to "live sync" their local CouchDB with my Cloud based CouchDB and use the app online on all their devices. They can also configure CouchDB to live sync their DB with 3rd party services like Couchbase and Cloudant and create backups and snapshots of all their data on those 3rd party services with their local CouchDB.
