Cloud-native vector database for scalable ANN search

When your app converts text or images into numerical vectors (via OpenAI, Cohere, or any embedding model), Milvus finds the closest matches across millions or billions of vectors in milliseconds. Apache 2.0, Go/C++.

High-performance vector database and search engine

Qdrant is a vector database built for finding things by meaning rather than exact keywords. You store embeddings (the numerical representations that AI models produce from text, images, or any data), and Qdrant finds the most similar ones instantly.

Data infrastructure for AI

Store text, images, or any data as embeddings (numerical representations that capture meaning), then query for 'things similar to this.' It's the database layer that makes RAG (retrieval-augmented generation, feeding relevant documents to an LLM) work. Apache 2.0, rewritten in Rust for performance.

Open-source vector database

Weaviate is a vector database built for AI-native search and retrieval. Instead of matching exact keywords, it stores data as mathematical representations (vectors) and finds things that are semantically similar.
