Rust-built vector database with the best self-host story
Qdrant is open-source, Rust-built, and runs as comfortably on a single VM as on a Kubernetes cluster. Performance per dollar at large scale (>100M vectors) consistently beats managed offerings. Cloud product is solid but the OSS path is genuinely production-grade. Best for teams that want self-host control without paying the Weaviate ops complexity tax.
gRPC + Rust is the production combo.
We saturate a single Qdrant node at 8K QPS on a 32-core box with 200M vectors. Pinecone serverless was 4x more expensive at this scale. Memory profile is the unsung win.
Performance per dollar is unmatched.
Migrated from Weaviate. 30% faster queries on the same hardware. Backup story is simpler. Worth the migration cost.
OSS quality you can actually run in prod.
Many OSS vector DBs are demo-grade. Qdrant is one of two we trust in prod (Weaviate being the other). Single-node deploy got us to 50M vectors before clustering.
