How to Choose a Vector Databases Tool
Key criteria to evaluate when comparing Vector Databases solutions:
About Chroma
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.
About Elasticsearch
Elasticsearch is the world's most widely deployed, open-source vector database, operated by Elastic N.V. (NYSE: ESTC). Vector search is integrated into the widely used Elasticsearch search and analytics engine, leveraging the mature ELK stack ecosystem and offering powerful filtering, aggregation, and combined keyword + vector (hybrid) search capabilities. Founded in 2012 in Amsterdam, Elastic provides a platform for enterprise search, observability, and security use cases. Recent innovations include DiskBBQ, a new disk-friendly vector search algorithm that delivers more efficient vector search at scale and eliminates the need to keep entire vector indexes in memory. Elasticsearch's pricing model is consumption-based, charging only for the compute, storage, and data transfer actually used across three deployment tiers: Standard, Platinum, and Enterprise. With over 470 customers using Elastic for AI (including 410+ using it as a vector database), Elasticsearch has proven capabilities at massive scale.
