Ladybug: Spreading its Wings

If you are a Kuzu user, it is high time you migrate to its vibrant successor, LadybugDB.

Since Kuzu was officially archived in October 2025, our team forked the repository to ensure the graph database ecosystem continues to thrive under LadybugDB with fixing security vulnerabilities and integrating with other data storage systems as a major focus. Over the last few months, we have introduced a massive array of features, performance improvements, and ecosystem expansions that make the v0.15 release our biggest milestone yet

So what’s new?

Massively Expanded Ecosystem

We’ve invested heavily in making LadybugDB accessible from anywhere. We now offer first-class bindings for the following languages:

Python (support for Python 3.14!)
Node.js
Rust
WebAssembly (Wasm) Try it in your browser
Java
Go
Swift
V-lang
Julia
Ruby (community)
Nim (community)

For a deep dive into using these APIs, check out our Client APIs Documentation.

Ladybug Subgraphs and External Data Architecture

Seamless External Database Support

Full support for seamlessly integrating Arrow, DuckDB, and Parquet datasets is here. Rather than migrating or converting your external data into native Ladybug tables, you can simply attach these databases and query them directly!

Here is how you can use an Arrow source transparently as a node table:

CREATE NODE TABLE Employee (id INT64, name STRING, PRIMARY KEY (id))
WITH (storage='arrow://my_arrow_table_id');

For parquet, take a look at the huggingface dataset

Subgraph Support

Creating and querying multiple graph namespaces just got a whole lot easier with true subgraph support. You can now define isolated graphs and switch contexts natively:

CREATE GRAPH my_graph;
USE my_graph;

You can also CREATE and MERGE nodes without creating a node table first

CREATE GRAPH my_graph ANY;
USE my_graph;
CREATE (u:User {name: 'Alice'});

A Better Way to Visualize: Bugscope

Monitoring your data should be pleasant. We’ve introduced Bugscope, a react-force-graph-2d based visualizer for LadybugDB.

Looking Ahead: Future Improvements

We aren’t stopping at v0.15. Here’s a quick peek at what’s coming next:

Native SQLite Support: Seamless querying across SQLite natively in LadybugDB
Advanced Arrow & Parquet Optimizations: Execution layer enhancements to handle even larger, more complex queries over columnar formats efficiently
Improved Compatibility with other Graph Databases: Multi-label support for ANY type graphs without compromising the strict schema and typing

We are incredibly excited about the state of LadybugDB and the incredible community rallying around the project. If you haven’t switched yet, there’s never been a better time to make the jump!
