Resource policies are now generally available in MongoDB Atlas. This release introduces seven new policies and a new graphical user interface (GUI) for creating and managing policies. These enhancements give organizations greater control over MongoDB Atlas configurations, simplifying security and compliance automation.
newsecurityNow GA: MongoDB Atlas Flex Tier
Introducing Atlas Flex tier, an ideal combination of elasticity and predictable pricing, suitable for MVPs and application development and testing. The Atlas Flex tier empowers developers with: Flexibility: 100 ops/sec and 5 GB of storage are included by default, as is dynamic scaling of up to 500 ops/sec. Predictable pricing: Customers will be billed an $8 base fee and additional fees based on usage. And pricing is capped at $30 per month. This prevents runaway costs—a persistent challenge with serverless architectures. Data services: Customers can access various features such as MongoDB Atlas Search, MongoDB Atlas Vector Search, Change Streams, MongoDB Atlas Triggers, and more. This delivers a comprehensive solution for development and test environments.Seamless migration: Atlas Flex tier customers can transition to dedicated clusters when needed via the MongoDB Atlas UI or using the Admin API. The Atlas Flex tier integrates the benefits offered by the previously available shared tier and serverless tier clusters.

NewNew! Atlas is now a part of MongoDB's Bug Bounty Program
MongoDB’s public bug bounty program now includes the free tier of MongoDB Atlas. Security researchers can submit reports for Atlas Free Tier through HackerOne, helping MongoDB identify and address potential vulnerabilities earlier in the development lifecycle. This expansion reinforces MongoDB’s commitment to proactive security and continuous improvement of its cloud offerings.
newsecurityNow GA: GraphRAG with MongoDB Atlas and LangChain
Now GA: The GraphRAG integration with MongoDB Atlas and LangChain combines a knowledge graph with LLMs to improve relationship understanding and reasoning. This results in more accurate and trustworthy outcomes in retrieval-augmented generation (RAG).
NewNow Generally Available: Automatic Quantization in Atlas Vector Search
Scaling applications to billions of vectors is now easier and more cost-effective. Implement scalar quantization and binary quantization with rescoring natively in Atlas Vector Search. Up to 96% memory reduction, high accuracy, and better query performance.
