Weaviate alternatives in detail

  1. Milvus

    open sourceApache-2.0Linux, macOS, WindowsPlatform

    Milvus is an open-source vector database engineered for scale — a distributed architecture that separates storage and compute and a broad set of index types (HNSW, IVF, DiskANN, GPU) for billion-vector search. Milvus Lite runs embedded for prototyping; Zilliz Cloud is the managed option.

  2. Pinecone

    freemiumWebPlatform

    Pinecone is a fully managed, serverless vector database: you call an API to upsert and query embeddings and never run a node, tune an index, or page yourself at 3am. It supports metadata filtering, hybrid search, and integrated embedding/reranking — the zero-ops choice when engineering time is the scarce resource.

  3. Qdrant

    open sourceApache-2.0Platform

    Qdrant is an open-source, Rust-based vector database for storing embeddings and running fast similarity search with rich payload filtering, hybrid (dense + sparse) search, and on-disk quantization — the retrieval store behind many production RAG systems.

  4. turbopuffer

    paidPlatform

    turbopuffer is a serverless vector and full-text search database built from first principles on object storage (S3, GCS, Azure Blob). Vectors and BM25 indexes live durably in cheap object storage and are cached on NVMe/RAM only when queried, so storage cost stays low at very large scale while hot data still serves fast. Pricing is usage-based across storage, writes, and queries.
