Show HN: LatticeDB – Like SQLite but for graph databases
LatticeDB is an embedded single-file graph database for local, relationship-heavy workloads. It unifies graph traversal, HNSW vector similarity, and BM25 full-text search in one query layer, with ACID transactions, WAL-backed durability, event streams, and graph changefeeds. Python, TypeScript, Go, and CLI access it. Benchmarks report sub-microsecond lookups and 0.83 ms 10-NN search at 1M vectors, but single-writer, single-machine design limits scaling.
