MongoDB Atlas alternatives

MongoDB Atlas is a document database, so the closest alternative depends on why you are moving. For Postgres, compare Neon, Supabase and PlanetScale. Firebase is Google's backend platform for mobile and web apps.
When MongoDB Atlas is not a good fit
MongoDB Atlas is MongoDB Inc's managed cloud database service for the MongoDB document database, running on AWS, Azure or Google Cloud. It offers a permanently free M0 tier, a low-cost Flex tier for development and unpredictable workloads, and Dedicated tiers for production, plus add-ons like Atlas Search and Vector Search. Pricing is usage-based, driven mainly by cluster tier, storage and data transfer.
It is a weaker choice for:
- Teams committed to a relational (SQL) data model, since MongoDB is a document database
- Cost-sensitive, high-storage workloads where dedicated tier pricing can grow quickly compared to self-managed alternatives
- Projects that need the community, self-hosted MongoDB Community Edition rather than a managed cloud service
