## Useful for

- Add long-term memory to an LLM agent by saving embeddings to a single .nvec file
- Replace ChromaDB or FAISS in a LangChain chain with a lightweight local index
- Run exact top-k search over 50,000 vectors with metadata filtering

## Why it’s here

- The repository is 18 days old and already has 6 stars.
- Hacker News: “Show HN: NanoVector – A 120KB zero-dependency vector search engine in C and SIMD” — 10 points, 17 days ago.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
