Multi Tenant Project Based Authorization And Resource Sharing

via “role-based access control (rbac) with permission domains and multi-tenancy”

Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database​.

Unique: Implements permission domains enabling fine-grained access control at collection and object level, not just role-based. Multi-tenancy is first-class with tenant-specific RBAC policies and data isolation.

vs others: More granular than Pinecone's API key-based access because it supports role-based permissions; better multi-tenancy than Milvus because tenant isolation is built-in rather than application-level.
