Self-managed Enterprise Advanced is quoted by sales.

Does MongoDB have a free plan?

Yes. MongoDB offers a free tier with limits; paid plans unlock higher usage or team features.

What are the main drawbacks of MongoDB?

The trade-offs we noted: RAM Consumption: Can be heavy on memory usage as it likes to process data in RAM.; Relational Data: Not as efficient as SQL databases for tasks requiring many 'JOINs'.; Data Integrity: While ACID-compliant now, SQL is still often preferred for banking data..

When should you not use MongoDB?

Skip MongoDB if: You need backups on the free tier — M0 has none; Your workload is heavy: M30 is about $387/month and M50 about $1,440/month before storage, transfer and search add-ons; You want on-premises Enterprise Advanced with a listed price; it is quoted by sales.

MongoDB

Modern NoSQL database.

What it is

MongoDB is the world's most popular NoSQL database, storing data in flexible, JSON-like documents (BSON). It aligns perfectly with modern object-oriented programming, allowing for rapid development without rigid schema requirements. Its 'Atlas' cloud service automates database management and provides global backups. It is ideal for large datasets and fast-evolving application structures where agility is key.

Dev and test environments on Flex, $0.011/hour (about $8–$30/month) with 5 GB
Production apps that need dedicated clusters from $0.08/hour (M10, about $57/month)

Skip it if

You need backups on the free tier — M0 has none
