txtai
💡 All-in-one open-source embeddings database for semantic search, LLM orchestration and language model workflows
-
deeplake
Database for AI. Store Vectors, Images, Texts, Videos, etc. Use with LLMs/LangChain. Store, query, version, & visualize any AI data. Stream data in real-time to PyTorch/TensorFlow. https://activeloop.ai
Finally, we stored these vectors in our chosen database: the activeloop DeepLake database. This database is open source, something near and dear to our own open-source hearts. We will cover some additional details in a further section, but it is specifically designed to handle vector data and perform efficient similarity searches, which is crucial for quick and accurate retrieval during the RAG process.

lancedb
Developer-friendly, serverless vector database for AI applications. Easily add long-term memory to your LLM apps!
Project mention: The Best Way to Use Text Embeddings Portably Is with Parquet and Polars | news.ycombinator.com | 2025-02-24For another library that has great performance and features like full text indexing and the ability to version changes I’d recommend lancedb https://lancedb.github.io/lancedb/
Yes, it’s a vector database and has more complexity. But you can use it without creating indexes and it has excellent polars and pandas zero copy arrow support also.

deep-searcher
Open Source Deep Research Alternative to Reason and Search on Private Data. Written in Python.
Project mention: Deep Searcher, Open source deep researcher on your private data | news.ycombinator.com | 2025-02-21github https://github.com/zilliztech/deep-searcher
-
raptor
The official implementation of RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval
Project mention: RAPTOR: A Novel Tree-Based Retrieval System for Enhancing Language Models – Research Summary | dev.to | 2024-12-13This study introduces RAPTOR (Recursive Abstractive Processing for Tree-Organized Retrieval), a novel tree-based retrieval system designed to enhance search capabilities for extended language models.

Project mention: Ask HN: What Are You Working On? (February 2025) | news.ycombinator.com | 2025-02-23
I'm working on Airweave https://github.com/airweave-ai/airweave , an open-source dev tool that makes any app searchable for AI agents. it connects to a source app, db, or api and converts its contents to accessible knowledge for agents. Airweave automates authentication, ingestion, enrichment, mapping, and syncing to vector stores and graph databases of choice. you can use it via our UI, API, or SDKs https://docs.airweave.ai/
we originally built this for our previous agent startup as an internal solution to ensure agents could find the relevant data on apps they're using. We then pivoted to this after some early positive reactions and decided to open-source it.
here's a short demo: https://tinyurl.com/demo-airweave
we're two engineers/friends based in Amsterdam, NL. We just launched the project, so it's rough around the edges ofc, but we're very eager to get some feedback!
feel free to reach out to me personally if you like this!

Project mention: Show HN: Vicinity – Fast, Lightweight Nearest Neighbors with Flexible Back Ends | news.ycombinator.com | 2024-12-01
Not author of the library, but the documentation lists the backends here: https://github.com/MinishLab/vicinity?tab=readme-ov-file#sup...
So these are nearest neighbor search implementations, not database backends.
