Pricing
FreemiumMongoDB Atlas Vector Search is not a separately priced product; it runs on your existing Atlas cluster resources. The Free tier (M0) offers 512MB of storage and supports basic vector search for learning and prototyping at no cost. The Flex tier costs between $8 and $30/month (usage-capped, pay-as-you-go hourly), suitable for low-to-moderate production workloads and replacing the deprecated Shared and Serverless tiers as of February 2025. Dedicated clusters start at $57/month for entry-level production workloads, with hourly rates that vary by cloud provider (AWS, Azure, GCP) and region. For production workloads needing isolated vector search performance, dedicated Search Nodes (requiring a minimum of two nodes on an M10+ cluster) are billed separately, ranging from roughly $0.12/hour for an S20 node up to $4.22/hour for the largest S80 tier. Data transfer/egress is billed separately at standard per-GB cloud provider rates, and self-managed Enterprise Advanced deployments require a custom sales quote. Serverless instances were fully retired on January 22, 2026, with existing customers migrated to Free, Flex, or Dedicated tiers.
FreemiumQdrant's Free Tier is free forever, offering a single-node cluster with 0.5 vCPU, 1GB RAM, and 4GB disk, plus free cloud inference with selected models, ideal for testing and prototypes. The Standard Tier uses usage-based pricing for production workloads, billed hourly based on compute (vCPU), memory (GB), storage (GB), backup storage, and used inference tokens for paid models; it includes dedicated resources, flexible vertical and horizontal scaling, high availability setups, backup and disaster recovery, and a 99.5% uptime SLA. The Premium Tier requires a minimum spend and adds SSO, private VPC links, a 99.9% uptime SLA, and extra support for enterprises with additional security and compliance needs, available by contacting sales. Qdrant Hybrid Cloud lets teams run managed Qdrant clusters on their own infrastructure for local data residency and regulated workloads, while Private Cloud offers a fully isolated, air-gapped deployment for large enterprises; both require contacting the Qdrant team for pricing. The open-source Qdrant engine itself remains free and self-hostable under an Apache 2.0 license.

Summary
Build intelligent applications with vector search, hybrid search, and generative AI on your live data
Open-source vector search engine for production-grade AI retrieval
MongoDB Atlas Vector Search Pros & Cons
Pros
- Unified data model eliminates the sync overhead of running a separate standalone vector database
- Search Nodes let you scale vector search compute independently from your core transactional workload
- Automated Embedding (powered by Voyage AI) generates and syncs embeddings with zero ML pipeline setup
- Free M0 tier makes it genuinely possible to prototype RAG and semantic search at zero cost
- Backed by a mature, public company (Nasdaq: MDB) with 125+ global regions and enterprise-grade security
Cons
- Dedicated Search Nodes require an M10+ cluster minimum, adding cost before you get isolated vector search compute
- Vector embeddings must stay under a 4096-dimension limit, which can constrain some newer, higher-dimensional embedding models
- Usage-based pricing across compute, storage, Search Nodes, and data transfer makes total cost harder to predict than a flat-rate competitor
- Best value requires already using or being willing to adopt MongoDB as your primary operational database, not just a vector store
- Serverless instances were retired in January 2026, forcing migrated customers to re-evaluate Free, Flex, or Dedicated tiers
Qdrant Pros & Cons
Pros
- Free forever tier with no time limit, ideal for testing and small projects
- Open-source core under Apache 2.0 with full self-hosting flexibility
- High-performance Rust architecture built for real-time, large-scale vector search
- Native hybrid dense-sparse search and advanced filtering in a single query
- Flexible deployment across managed cloud, hybrid, private, and edge environments
- SOC 2 and HIPAA compliant with strong enterprise security options
Cons
- Standard and Premium Cloud tiers use usage-based or minimum-spend pricing rather than flat, published rates
- Premium tier features like SSO and private VPC links require talking to sales for pricing
- Self-hosting the open-source engine requires managing your own infrastructure and scaling
- As a specialized vector database, it requires pairing with separate embedding models and application logic
- Some advanced enterprise features like custom SLAs are only available through Hybrid or Private Cloud contracts
