Ladybug is an embedded, serverless graph database (a community successor to Kuzu) written in C++, using a property graph data model and the Cypher query language. It features columnar storage, vectorized query execution, ACID transactions, full-text search, vector indices, and client bindings for Python, Node.js, Rust, Go, Swift, Java, C/C++, and WebAssembly.

Use cases

• run analytical Cypher queries on large graphs inside my application
• embed a graph database without running a server
• store and query knowledge graphs of code or documents
• add vector similarity search to graph data for RAG
• replace KuzuDB after its development stopped
• query graph data from Python or Node.js
• run graph analytics on Parquet or Arrow data
• build agentic AI apps with an embedded graph store

When to choose

• you need an embedded, dependency-free graph database with Cypher support
• you run join-heavy analytical workloads on large graphs
• you want full-text and vector search alongside graph queries
• you need a maintained KuzuDB successor
• you want in-process ACID transactions with multi-core parallelism

When to avoid

• you need a distributed, multi-node graph database server
• you primarily need simple relational queries better served by DuckDB or SQLite
• you need a mature ecosystem of graph visualization tooling
• you require long-term enterprise support guarantees from a large vendor
