Here is everything you need to know about using MongoDB Community Edition for your business. MongoDB Community Edition is free for commercial use.
MongoDB got tired of this. They created the Server Side Public License (SSPL) . The SSPL explicitly closes the cloud loophole. It states: If you offer MongoDB as a service to third parties, you must open source all the management software, APIs, and infrastructure code you use to host it.
It is a fair question. In the world of databases, "free" often comes with landmines. Some databases are free only for development. Others are free until you use clustering. Others are "open source" but restrict cloud usage.
Monitoring and Automation. Running MongoDB Community at scale is doable, but you have to build your own monitoring dashboards (Prometheus/Grafana) and your own backup scripts. MongoDB Enterprise gives you Ops Manager, which is a massive time-saver. The "Atlas" Question Many developers ask: "If I use MongoDB Atlas (MongoDB's cloud), is that the free version?"
