KGLite is an embedded, Cypher-queryable knowledge graph engine for Python and Rust, designed to serve applications, analysts, and LLM agents without an external database. It offers advanced features like schema-aware descriptions for LLMs, temporal querying over historical data, and a declared ontology for data quality.

Features

01Progressive-disclosure schema (`describe()`) optimized for LLM context windows.
02As-of queries over historical data using `valid_at()` and `valid_during()` functions.
03Declared ontology with data-quality gates and audit scorecards for semantic integrity.
04Hybrid retrieval combining vector similarity (`text_score()`) with Cypher traversal.
05Embedded, in-process graph engine with various storage modes (in-memory, mmap, disk).

Use cases

↳Providing domain knowledge (legal precedents, regulatory rules, medical ontologies) for LLM agents.
↳Transforming business data from tabular sources (SQL, CSV, DataFrames) into a queryable graph.
↳Structuring RAG corpora with documents, chunks, entities, and their relationships for hybrid retrieval.
↳Codebase analysis by parsing code into a graph of functions, classes, and modules.
↳Ingesting Markdown knowledge bases (Obsidian vaults, Claude memory) into a queryable graph for analysis and agent memory.
