Qdrant
Qdrant is a vector similarity search engine with an API for storing, searching, and managing vectors alongside payload data. Points can include JSON metadata that helps filter search results. It supports dense, sparse, and multivector configurations, plus hybrid retrieval that combines semantic and lexical search. These capabilities can support semantic search and recommendation systems. You can run Qdrant locally using its Docker image or use Qdrant Cloud. It provides REST and gRPC APIs and official client libraries for Python, JavaScript/TypeScript, Rust, Go, .NET, and Java. Listed integrations include LangChain, LlamaIndex, Airbyte, Unstructured, DocArray, and AutoGen. The free cloud tier is intended for testing and prototypes, with a single-node cluster limited to 1GB RAM and 4GB disk. Qdrant Cloud enables TLS and encryption at rest; self-hosted deployments require configuration for these protections, and open-source self-hosted deployments do not enable authentication or encryption by default. The maker is headquartered in Berlin and was founded in 2021.
