Zvec
Embeddable vector database that runs inside your application process
What it is
Zvec is a C++ vector database library that lives in your program's process instead of running as a separate server. It keeps dense and sparse embeddings on disk with write-ahead logging, and a single query can mix similarity search, keyword text matching, and filters on structured fields. Developers building RAG pipelines, agent memory, or local semantic search call it from Python, Node.js, Go, Rust, or Dart without setting up any infrastructure.
