Why we included this project
DBreeze is worth a look for .NET teams that want an embedded database with vector search instead of running a separate service. It is an ACID-compliant, transactional key-value store that also handles text search, multi-parameter search, and object storage, with a vector layer for similarity search on embeddings. Keeping vectors and their metadata in one engine saves you from wiring together two databases. The library ships as a .NET package that runs on Linux, Windows, and macOS, plus mobile targets through Xamarin and Unity, and it has been in production use since 2012. If you need a lightweight, embeddable option for vector workloads in .NET, this is a solid candidate.
