Weaviate
Weaviate is an AI database that enables developers to build search, retrieval-augmented generation (RAG), and agentic AI applications with less hallucination and data leakage. It handles embeddings, ranking, and auto-scaling out of the box, supporting Python, Go, TypeScript, JavaScript, GraphQL, and REST APIs. Deploy on Weaviate's cloud, AWS, Google Cloud, or your own infrastructure with enterprise-grade security including HIPAA compliance and RBAC.
Weaviate is an AI-native database purpose-built for developers creating search, retrieval-augmented generation (RAG), and agentic AI applications. It consolidates embeddings, ranking, and auto-scaling into a single system, eliminating the need for complex data pipelines and separate infrastructure components. The platform supports Python, Go, TypeScript, and JavaScript SDKs alongside GraphQL and REST APIs, with seamless integration of ML models—either custom or via Weaviate's built-in embedding service. Developers can deploy on Weaviate's managed cloud, AWS, Google Cloud, or self-hosted infrastructure, with enterprise-grade security including RBAC, SOC 2 compliance, and HIPAA certification for AWS environments. The architecture scales to billions of vectors while optimizing costs, and pre-built database agents reduce manual work by automating data interactions. With over 20 million open-source downloads and customers including Morningstar, Booking.com, Intuit, and Cisco, Weaviate enables teams to ship AI features faster while reducing hallucination and data leakage risks.

No training opt-out mechanism was identified in the legal documents.
Moderate risk. Suitable for internal data but avoid confidential information.
Weaviate collects aggregated and anonymized data for product improvement but explicitly states it does not train on individual customer data. However, the broad language around 'aggregated statistics' and 'product improvement' creates moderate risk for shadow AI use cases where data could potentially be used for model training.
“Weaviate shall have the right to aggregate, collect, and analyze data and other information relating to the provision, use, and performance of the Weaviate Offering and shall be free to use such data to develop and improve the Weaviate Offering”
The license grants are relatively narrow for customer data (customer retains ownership), but Weaviate retains broad rights to feedback and aggregated insights. The feedback clause grants Weaviate 'full, unencumbered right' to use feedback without compensation, which is moderately risky.
“Weaviate will have the full, unencumbered right, without any obligation to compensate or reimburse Customer, to use, incorporate, and otherwise fully exercise and exploit any such Feedback”
Data is shared with third parties for support, analytics, and cloud providers. Cloud metadata may be shared with cloud providers. Newsletter data is shared with third-party automation providers. This is moderate risk but limited to operational necessity.
“We may share cloud metadata with your cloud provider for the purpose of enabling them to contact you regarding Weaviate support, maintenance, or hosting services”
The terms do not specify explicit data retention periods for most data types. System Data and aggregated statistics can be retained indefinitely. Customer Data ownership is clear but deletion procedures are not detailed, creating moderate uncertainty.
“Weaviate shall have the right to aggregate, collect, and analyze data and other information relating to the provision, use, and performance of the Weaviate Offering and shall be free (during and after the term hereof)”
The terms clearly state that Weaviate exclusively owns the Weaviate Offering and System Data, while Customer exclusively owns Customer Data and outputs. IP ownership is well-defined with minimal ambiguity.
“Weaviate exclusively owns all right, title, and interest in and to the Weaviate Offering, System Data, and Weaviate Confidential Information, while Customer exclusively owns all right, title, and interest in and to the Customer Data”
The terms reference GDPR compliance and mention data protection legislation, but do not explicitly list SOC2, HIPAA, or ISO certifications. Insurance requirements are specified but compliance certifications are not detailed in the provided text.
“Weaviate is responsible for the collection and use of your personal data as described in this privacy policy in accordance with applicable personal data protection legislation”
