Ladybug

Ladybug is an embedded graph database built for query speed and scalability. Ladybug is optimized for handling complex analytical workloads on very large databases and provides a set of retrieval features, such as a full text search and vector indices. Our core feature set includes:

Flexible Property Graph Data Model and Cypher query language
Embeddable, serverless integration into applications
Native full text search and vector index
Columnar disk-based storage
Columnar sparse row-based (CSR) adjacency list/join indices
Vectorized and factorized query processor
Novel and very fast join algorithms
Multi-core query parallelism
Serializable ACID transactions
Wasm (WebAssembly) bindings for fast, secure execution in the browser

Ladybug is being developed by LadybugDB Developers and is available under a permissive license. So try it out and help us make it better! We welcome your feedback and feature requests.

The database was formerly known as Kuzu.
