Top 13 vector-search Open-Source Projects

  • milvus

    Vector database for scalable similarity search and AI applications.

    Project mention: Calvin and Hobbes Search Engine | | 2022-07-20

    I remember this from a while back - good to bring back memories. This may be a bit excessive, but using CLIP ( or some other multimodal learning model in conjunction with Milvus ( could make for a search engine that takes the graphics into consideration as well. Not sure how well it would work for comics, but it could make for a pretty unique weekend hack.


    A distributed approximate nearest neighborhood search (ANN) library which provides a high quality vector index build, search and distributed online serving toolkits for large scale vector search scenario.

    Project mention: Better text search | | 2022-05-04
  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • Weaviate

    Weaviate is a cloud-native, modular, real-time vector search engine

    Project mention: [D] Mining restaurant reviews for vibe | | 2022-05-20

    If I needed to get up an running quickly, and it was just me working on it, I'd roll with Weaviate.

  • txtai

    💡 Build AI-powered semantic search applications

    Project mention: In Praise Of SQLite | | 2022-07-28

    I've done that in txtai. It combines Faiss with SQLite and can be run as part of a distributed cluster.

  • hora

    🚀 efficient approximate nearest neighbor search algorithm collections library written in Rust 🦀 .

    Project mention: An efficient library for nearest neighbor search in native rust | | 2022-03-27
  • qdrant

    Qdrant - Vector Search Engine for the next generation of AI applications

    Project mention: Nearest Neighbor Embeddings Search with Qdrant and FiftyOne | | 2022-07-21

    Qdrant is an open-source vector database designed to perform an approximate nearest neighbor search (ANN) on dense neural embeddings which is necessary for any production-ready system that is expected to scale to large amounts of data.

  • vearch

    A distributed system for embedding-based vector retrieval

  • MoTIS

    Mobile(iOS) Text-to-Image search powered by multimodal semantic representation models(e.g., OpenAI's CLIP). Accepted at NAACL 2022. (by DRSY)

    Project mention: [D] Are there any apps that run model inference on the mobile device (Android or iPhone) itself? | | 2021-10-24

    I personally is maintaining an iOS app which enables users to search photos with text query using cross-modal retrieval. Github repo is here:

  • Nuclia DB

    NucliaDB is a cloud-native database for unstructured data, indexing vectors, text, paragraphs and relations.

    Project mention: qdrant VS nucliadb - a user suggested alternative | | 2022-07-18
  • alvd

    alvd = A Lightweight Vald. A lightweight distributed vector search engine works without K8s.
