Key criteria to evaluate when comparing Vector Databases solutions:
Chroma is an open-source embedding database designed for simplicity and developer experience, licensed under Apache 2.0. It provides a lightweight, easy-to-use API for storing, querying, and filtering embeddings locally or in the cloud.
Chroma is the default vector store in many LLM frameworks like LangChain and LlamaIndex, making it extremely popular for prototyping and building RAG applications quickly. The managed Chroma Cloud service offers serverless deployment with usage-based pricing, while the self-hosted version runs on a single node at no cost.
The company achieved SOC 2 Type II compliance for enterprise deployments and offers Chroma Cloud with features including BYOC in your VPC, multi-cloud/multi-region replication, and point-in-time recovery. Chroma is rated 4.2/5 on G2.
SingleStore is a real-time, unified, distributed SQL database that combines transactional, analytical, and vector data workloads in a single platform. MySQL and MongoDB wire protocol-compatible, SingleStore enables organizations to scale from one to one million customers, handling SQL, JSON, full text, and vector workloads all in one unified platform. Unlike traditional vector databases, SingleStore stores vector data in relational tables alongside other types of data, allowing easy querying of extended metadata and other attributes with the full power of SQL. The system supports both semantic search using FLAT, IVF_FLAT, IVF_PQ, IVF_PQFS, HNSW_FLAT, and HNSW_PQ vector indexes, with dot product and Euclidean distance for similarity matching. Founded in 2011 and headquartered in San Francisco, SingleStore serves hundreds of customers including 100+ Fortune 500, Forbes Global 2000, and Inc. 5000 brands. The company was acquired by Vector Capital in September 2025.
Purpose-built databases for storing, indexing, and querying high-dimensional vector embeddings used in semantic search, RAG, and recommendation systems.
