## What it is
Kuzu is an embedded, serverless property graph database written in C++ that implements the Cypher query language and is optimized for fast analytical queries on large graphs. It includes built-in full-text search, vector indices, columnar storage, and WebAssembly bindings for running in the browser.

## Use cases
- embed a graph database in my application without running a server
- run Cypher queries locally like SQLite but for graphs
- add vector similarity search to a knowledge graph
- build a RAG pipeline with graph + vector retrieval
- run a graph database in the browser with WebAssembly
- analyze large graphs with fast joins and parallel queries
- find a lightweight Neo4j alternative

## When to choose
- you need an embeddable, serverless graph database with Cypher support
- you want combined graph, full-text, and vector search in one engine
- you need fast analytical graph workloads on large datasets
- you want a database that runs in-browser via WebAssembly

## When to avoid
- you need a maintained project with active support - Kuzu has been archived by its maintainers
- you rely on official extension downloads - the extension server is no longer provided
- you need a client-server multi-user production database
- you require guaranteed long-term updates or security patches
