I created a “bread” browser application (browse/read/edit/add/delete) for querying and editing Couchbase documents.
I chose “bread” rather than “crud” (create/read/update/delete) only because it sounds a little better.

The README.md file describes how to setup/install it and run it.
It is intended to run on your local workstation rather than be deployed to a server to avoid additional security features.
Also the Node.js console log provides additional details to supplement any browser alerts that appear.
A team mate and I have been using this for about a month to query our development and production Couchbase instances. We have found and fixed some nuisance bugs during that time.
