Score: 6.3/10 (Innovation: 6, Technical: 8, Documentation: 7, Utility: 4)

Sana is an open-source vector database that stores documents directly on object storage like S3, inspired by turbopuffer. It combines vector search, full-text search, and attribute filtering with a durable WAL and delta-tiered indexes, making it architecturally interesting for understanding search infrastructure on cheap storage. The project is explicitly experimental and AI-assisted, limiting immediate production utility but offering strong technical depth and learning value.

Target audience: backend devs, data engineers
