Weaviate

Weaviate is an open source vector database that stores data objects together with their vector embeddings, and combines vector search with filters on structured data. It is written in Go and can be started from a Docker image or from a binary download. The sample Docker Compose file mounts a persistent volume at /var/lib/weaviate, where the server keeps its data.

The company behind it, Weaviate B.V., is established in Amsterdam, the Netherlands.

Worth knowing

The project is open core. Code in the wl directory is available only under a commercial license, and its enterprise features run with a license key. Weaviate Cloud is a managed service that uses the same open source project, offered beside the self-hosted server.
