Weaviate

Weaviate is an open-source, AI-native vector database designed to power search, retrieval-augmented generation (RAG), and agentic AI applications. It enables developers to store, index, and query high-dimensional vector embeddings alongside traditional data, making it ideal for building intelligent applications that require semantic understanding. With over 20 million open-source downloads and thousands of customers, Weaviate serves as a core infrastructure component for startups, scale-ups, and enterprises building AI-powered products.

• Hybrid Search combines vector similarity search with keyword-based search, allowing developers to leverage both semantic understanding and exact matching for optimal retrieval results.

• Built-in Embeddings provides native embedding services and integrations with major model providers including OpenAI, Cohere, Google, AWS, and Hugging Face, eliminating the need for separate embedding pipelines.

• Multi-tenancy Support enables efficient data isolation for SaaS applications, allowing thousands of tenants to share infrastructure while maintaining strict data separation.

• Vector Compression offers multiple quantization techniques (including rotational quantization) to reduce memory requirements by up to 4x while maintaining search accuracy.

• Weaviate Agents includes pre-built agents like Query Agent, Transformation Agent, and Personalization Agent that automate common database operations and enhance data interactions.

• Flexible Deployment Options supports shared cloud, dedicated cloud, and self-hosted deployments across AWS, GCP, and Azure with enterprise-grade security including RBAC, SSO/SAML, HIPAA compliance, and PrivateLink.

• Language-agnostic SDKs provide client libraries for Python, Go, TypeScript, and JavaScript, plus GraphQL and REST APIs for seamless integration into any tech stack.

• Scalable Architecture handles billion-scale vector workloads with dynamic indexing, replication, and auto-scaling capabilities to grow with your application needs.
