Show HN: LatticeDB – Like SQLite but for graph databases

LatticeDB is an embedded, single-file graph database that combines graph traversal, vector similarity search, and full-text search in a unified query language, designed for relationship-heavy workloads on local machines without requiring server setup or configuration. It offers fast performance with capabilities like 0.13 microsecond node lookups and vector search across millions of vectors, with applications in Graph RAG, agent memory, and knowledge tools. The project is available with bindings for multiple languages including Python, TypeScript/Node.js, and Go.
