sqlitegraph 0.1.1

Embedded graph database with HNSW vector search — Python bindings to the sqlitegraph Rust crate.

sqlitegraph

Python bindings to the sqlitegraph embedded graph database. Storage, graph algorithms, and HNSW vector search run in a reviewed Rust core; this package is the Pythonic surface.

Alpha — API subject to change before 1.0.

Install

pip install sqlitegraph

Quick start

from sqlitegraph import Graph

g = Graph.open_in_memory()
alice = g.add_node(kind="User", name="Alice", data={"age": 30})
order = g.add_node(kind="Order", name="Order-123")
g.add_edge(alice, order, "placed")

print(g.neighbors(alice))
