MongoDB Cloud Manager vs DB: What are the differences?
Developers describe MongoDB Cloud Manager as "A hosted platform for managing MongoDB *". It is a hosted platform for managing MongoDB on the infrastructure of your choice. It saves you time, money, and helps you protect your customer experience by eliminating the guesswork from running MongoDB. On the other hand, *DB** is detailed as "Version control for databases: save, restore, and archive snapshots of your database from the command line". With DB you can very easily save, restore, and archive snapshots of your database from the command line. It supports connecting to different database servers (for example a local development server and a staging or production server) and allows you to load a database dump from one environment into another environment.
MongoDB Cloud Manager and DB are primarily classified as "Cloud Management" and "Database" tools respectively.
DB is an open source tool with 893 GitHub stars and 17 GitHub forks. Here's a link to DB's open source repository on GitHub.
