About this API
MongoDB Atlas is MongoDB Inc. (founded 2007, IPO 2017) official managed cloud service, the de-facto standard for enterprise MongoDB deployment. MongoDB itself is the most popular NoSQL document database — data is BSON documents instead of SQL rows, flexible schema, natural fit with frontend JS objects. Atlas adds several products: (1) Atlas Search — Lucene-based full-text search, originally needed separate Elasticsearch now MongoDB built-in; (2) Atlas Vector Search (2023+) — built-in vector search (MongoDB's version of pgvector in Postgres), RAG apps without Pinecone; (3) Atlas Charts — built-in data visualization; (4) App Services — backend-as-a-service framework (formerly Realm). Multi-cloud deployment (AWS / GCP / Azure region selection). Free M0 tier provides 512MB DB shared cluster, enough for dev/POC. Production recommends dedicated cluster.
What you can build
- 1MongoDB applications cloud-hosted

FAQ
Atlas Vector Search vs. Pinecone?+
Already on MongoDB: Atlas Vector Search (no new component). Pure vector search: Pinecone has better performance.
MongoDB vs. Postgres?+
JSON documents / flexible schema: MongoDB. Complex relations / strong consistency / SQL: Postgres.
