Score: 6.5/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 6)

PulseDB is an in-memory database combining Redis-compatible key-value storage with an HNSW-based vector search engine, enabling hybrid queries with pre-filtering. Its integration with LangChain and support for the RESP2 protocol make it a compelling unified alternative to running separate Redis and Pinecone instances.
