ChromaDB
PyPIchromadbChromaDB is an open-source, embedded vector database popular in prototype and production RAG applications. It can run fully in-memory, as a local persistent store, or as a server. Its lightweight footprint makes it the default vector store in most LangChain and LlamaIndex quickstarts, meaning it appears in a large fraction of LLM application repositories.

}Why this package is monitored
Embedded database libraries have direct filesystem access to the local data store. A malicious publish can read all stored embeddings and associated document metadata from the local persistence directory without making any network requests.
