Embedded single-file knowledge graph database with vector search and full-text search for AI/RAG apps
That same week, a Show HN called LatticeDB landed: an embedded, single-file property-graph database written in Zig, positioned as "like SQLite but for graph databases," with native HNSW vector search and BM25 full-text search in the same query layer. The marketing number going around is up to 2,819x faster graph traversal than SQLite. Numbers like that are usually a sign to keep scrolling. This time I did not. I read the benchmark methodology, then rebuilt the SQLite side myself and ran it on my own server.
