How to Choose a Vector Databases Tool
Key criteria to evaluate when comparing Vector Databases solutions:
About Milvus
Milvus is an open-source vector database built for scalable similarity search, capable of handling billions of vectors in distributed environments. Created by Zilliz, a company founded in 2017 by Charles Xie (former founding engineer of Oracle 12c cloud database), Milvus has become one of the most widely deployed vector databases with over 30,000 GitHub stars.
The database supports multiple index types including IVF, HNSW, and DiskANN, with GPU-accelerated search and hybrid search combining dense and sparse vectors in a single query. Milvus runs on Kubernetes for production deployments and is governed under the LF AI & Data Foundation. Zilliz Cloud offers a fully managed version with automatic scaling, starting with a free tier and usage-based pricing from $4 per million vector compute units.
Zilliz has raised approximately $113-132 million in funding, with a $60 million Series B extension in August 2022 led by Prosperity7 Ventures (Aramco). The company is headquartered in San Francisco with roughly 140 employees. Zilliz was named "Highest Performer" and "Easiest to Use" in G2's Summer 2025 Vector Database Grid Report.
About Pinecone
Pinecone is the most widely used managed vector database, purpose-built for similarity search and retrieval-augmented generation (RAG). Founded in 2019 by Dr. Edo Liberty, former Head of Amazon AI Labs at AWS, Pinecone offers serverless and pod-based architectures supporting billions of vectors with single-digit millisecond query latency.
The platform provides metadata filtering, namespaces, and hybrid search combining dense and sparse vectors. Its managed service eliminates infrastructure complexity, making it the go-to choice for teams building semantic search, recommendation engines, and RAG-powered AI applications.
Headquartered in New York City with 138 employees, Pinecone has raised $138M in total funding including a $100M Series B at a $750M valuation. The company serves over 4,000 customers and is rated 4.7/5 on G2.
