Valori – A Python-native Vector Database I built from scratch

I’ve been working on a project called Valori, a Python-native vector database I built from the ground up — not by reinventing every algorithm, but by wiring together efficient, well-known indexing and search techniques into a cohesive, hackable framework.

The idea came from my frustration with existing vector DBs that were either too heavy for experimentation or too opaque to modify. I wanted something simple, modular, and extensible — so I built it.

What it does:

Lets you store, index, and search high-dimensional vectors

Supports multiple indices (Flat, HNSW, IVF, LSH, Annoy)

Has memory, disk, and hybrid storage backends

Includes a full document processing pipeline (parsing, cleaning, chunking, embedding)

Offers quantization, persistence, and plugin-based extensibility

All written in Python, integrated with NumPy, and production-tested with logging and monitoring built in.

Install:

pip install valori

I’d love to hear your thoughts —

What’s missing for you in current vector DBs?

If you’ve built LLM or RAG systems, what do you wish a lightweight, pure Python DB like this handled better?

Would you prefer tighter integrations (LangChain, Haystack, etc.) or a more “build-it-yourself” style?

Feedback, criticism, or collaboration ideas are all welcome. — Varshith ([email protected] )
