real-ladybug

What it is and what it does

Real-ladybug is a Python binding for Ladybug, an embedded graph database designed to run directly within applications without a separate server. It implements a property graph model with Cypher query language support, allowing you to store and query complex relational data as nodes and edges. The database is optimized for analytical workloads on large datasets, combining columnar disk-based storage with specialized index structures (full-text search, vector indices, and sparse row-based adjacency lists) to accelerate query execution.

The package provides serverless, embeddable integration—you can create in-memory or file-backed databases and execute queries directly from Python without managing a separate database process. It includes multi-core query parallelism, ACID transactions, and WebAssembly bindings for browser execution. With no runtime dependencies beyond the precompiled binary, deployment is straightforward once the platform-specific wheel is installed.

Use it for:

• Build knowledge graphs or recommendation engines with full-text and vector search on large node/edge datasets.
• Run analytical queries on property graphs in embedded applications without deploying a separate database server.
• Prototype or deploy graph-based machine learning pipelines that require join operations and columnar storage.
• Query complex relational data using Cypher in a serverless, single-process context for edge computing or desktop tools.
• Combine semantic search with structured graph queries in applications requiring both capabilities.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Embeddable graph database with Cypher query support, full-text search, vector indices, and columnar storage optimized for analytical workloads on large datasets.

Yes, if you need an embeddable graph database with Cypher support and analytical query optimization. The permissive MIT license, active maintenance, zero runtime dependencies, and broad platform coverage make it low-risk to try. Medium install friction is acceptable for a compiled database engine. No known vulnerabilities. Best suited for applications that want graph querying without managing a separate database server.

Install

real-ladybug on PyPI

pip install real-ladybug

uv add real-ladybug

poetry add real-ladybug

Installing real-ladybug

Before you install

Medium install friction due to platform-specific wheels across multiple Python versions and architectures. No runtime dependencies simplifies deployment once installed. Active maintenance status supports ongoing compatibility.

License in practice

MIT license is permissive and allows use in commercial and proprietary projects with minimal restrictions; attribution required but no copyleft obligations.

Quickstart

pip install real_ladybug

import real_ladybug

# Create and query a graph database
db = real_ladybug.Database(':memory:')
conn = db.connect()
conn.execute('CREATE NODE TABLE Person(name STRING, age INT64)')

Precompiled wheels available for macOS (Intel/ARM), Linux (glibc/musl), and Windows; specific Python version requirements not documented in the fact sheet.

Verify before relying

• Exact Python version support and whether versions beyond those with available wheels are supported
• Performance characteristics of join algorithms and query processor relative to other graph databases
• Production-readiness guarantees and stability commitments beyond active maintenance status
• Typical use-case examples demonstrating scalability on real-world workloads
