Low Latency & Large-Scale

Achieve low latencies at any scale in production. Weaviate is a fault-tolerant, highly-available database that you can tune for the best possible QPS/Accuracy trade-off.

Flexibility

Use Weaviate as a stand-alone vector search engine (bring your own vectors) or use one of the many modules (transformers, GPT-3, and more) to vectorize or extend your Weaviate setup.

Ease-of-Use

Cloud-native (Kubernetes and Docker), a wide variety of client libraries, and available through RESTful and GraphQL APIs.
