Free and open-source alternatives to Pinecone

Pinecone alternatives in detail

  1. 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.

  2. Weaviate

    open sourceBSD-3-ClauseLinux, macOS, WindowsPlatform

    Weaviate is an open-source, Go-based vector database with first-class hybrid search, a module system that can vectorize your data for you, and GraphQL/REST/gRPC APIs. Batteries-included is the pitch: it can embed, store, filter, and hybrid-search out of the box, self-hosted or as a managed cloud.

  3. pgvector

    open sourcePostgreSQLLinux, macOS, WindowsSDK

    pgvector turns Postgres into a vector database: it adds a vector column type, distance operators, and HNSW/IVFFlat indexes so you can run similarity search next to your relational data, with full SQL filtering and transactions — no separate vector store to operate.

  4. 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.

  5. 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.
