Is MongoDB actually free to use?
Yes, MongoDB offers a free Community Server you can run yourself and a free Atlas tier (M0) for small cloud deployments. The free Atlas tier includes 512 MB of storage, but production workloads require a paid Atlas cluster or self-managed infrastructure.
What are the limits of MongoDB Atlas free tier?
The M0 free tier gives you 512 MB of storage, shared CPU/RAM, and a limited set of features. It lacks continuous backups, advanced security controls, and dedicated support, and idle clusters may be paused after 60 days of inactivity.
What are the main downsides of MongoDB compared to PostgreSQL?
MongoDB is weaker at highly relational joins, complex analytics queries, and strict schema enforcement. PostgreSQL can handle both relational workloads and JSON data, making it a stronger default for many traditional applications.
