Found a thread migrated from your old forum about this but unable to comment and Roger posted 10 months ago.
This is still on our todo list and is not yet scheduled for a specific release. I've added your vote for supporting MongoDB and you will be notified if we do something in this area.
We do not have a public feature request forum, but we have received a few requests for MongoDB support. Since it is not a SQL database, it is not completely clear how it would fit into DbVisualizer, though.
While we do not actively look at supporting it at the moment, we are aware of a few JDBC drivers that support MongoDB, mapping document collections to tables. One is the DataDirect driver: https://www.progress.com/connectors/mongodb, which we have heard works with DbVisualizer. There is also the Apache Drill project, which supposedly provides a JDBC driver for MongoDB: http://drill.apache.org.
You may want to try out one of those drivers. If you do, please let us know the result.
Had a quick go with both drivers. Neither allow you (in DbVisualizer) to Create a Collection (Table) or insert a Document (Record or Row) into an existing Collection (Table).
Just useful for browsing, but without above you may as well use "mongo" from the console/terminal/command prompt.
Nogo fact for drill:
1. not really usable under windows...too complicated to setup
2. also only static content if you use it in DBvis. Also readonly (no update,insert ect possible!)
