“Qdrant is not owned by xAI: it's an open-source library that they forked. The biggest benefit of Qdrant is performance (speed + recall), which trumps ElasticSearch handily in all benchmarks: https://qdrant.tech/benchmarks/ The other important aspect of vector stores like Qdrant is that they can index and filter on any metadata.”
“I use Qdrant for dense vector lookup. Right now I am experimenting with hybrid search and QDrant supports it but its a bit clunky, also the sparse vector (bm25) doesn't seems to be working well, but this might be an error on my end. My issue is Qdrant seems a bit slow even for very small collections, like 2s query time. I read about Weaviete, but that is too expensive Anyone else using qdrant, what are your thoughts?”
“We use Qdrant since one year as default vector db in the Cheshire Cat AI (open source also, it is an AI assistant framework). We chose Qdrant because: exists in file based, container based and cloud version vector/embedding focused easy to use and fast I'm not affiliated to them, I just think it is a great vector db”
“I worked extensively with both.pgVector:Pros: Amazing productivity, easily maintainable, and you get all the stability and upside of Postgres .Cons: Performance tend to be slightly behind Qdrant. At certain scale, becomes hard to work with. Qdrant:Pros: Best in class performance, flexible scaling.Cons: You will need 2 DBs, and this is a lot of engineering hours to get right. Overall, I like pgVector and I have a large open-source RAG API built on it. But, Qdrant is really good, and it feels like”

“it is optimized for speed and scalability, capable of handling large datasets with high throughput. The engine uses state-of-the-art algorithms to ensure fast query responses. High performance comes with high resource usage, which might be a consideration for smaller deployments. The straightforward API and comprehensive documentation make it easy to set up and use, even for those new to vector search engines.Highly customizable to fit specific needs, including various distance metrics and index”

“Self-hosting Qdrant on a host is really simple and does not takes a lot of time to setup or troubleshoot issues. The documentation is also up to date. I prefer to install it using Docker to avoid installing dependencies. The initial learning curve is high but the documentation and resources makes up for it. I mainly use Qdrant for searches and building applications where I need to store vectors”
“I work for Qdrant (https://qdrant.tech), and I can recommend checking it out! It offers both local and cloud, and recently we've introduced an in-memory mode, so you can use it for testing even without spinning a container: https://github.com/qdrant/qdrant-client#local-mode We've been experiencing a lot of migrations from the other tools recently, also due to the things you mentioned: https://twitter.com/qdrant_engine/status/1643609285782282241.”
“I use qdrant (and meilisearch) for my side project to browse Github Awesome Lists (https://awesome.facts.dev/). I self host both of those servers, it is very easy so far. I use the docker image for qdrant, worked without any problems.”

Questions
Frequently asked
What is Qdrant?
Qdrant is a vector database built in Rust that enables production-grade vector search for AI applications. It provides real-time indexing, hybrid search capabilities, and advanced metadata filtering for building RAG systems, AI agents, recommendation engines, and semantic search applications.
Is Qdrant free to use?
Yes, Qdrant offers a free tier that's available forever for testing and prototypes. The free tier includes a single node cluster with 0.5 vCPU, 1GB RAM, 4GB disk storage, and free cloud inference with selected models.
What makes Qdrant's hybrid search different from other vector databases?
Qdrant combines dense vector similarity with sparse keyword matching in a single query, supporting methods like BM25, SPLADE++, and miniCOIL. Unlike competitors, it performs filtering during HNSW traversal rather than pre- or post-filtering, enabling high recall with low latency under complex conditions.
How does Qdrant handle real-time updates?
Qdrant features real-time indexing where new vectors become searchable immediately without needing to rebuild existing indexes. This allows applications to continuously add new data while maintaining search performance without downtime.
What quantization options does Qdrant offer to reduce memory usage?
Qdrant supports asymmetric, scalar, and binary quantization techniques that can reduce memory usage by up to 64x while maintaining search quality. This makes it possible to handle larger datasets within memory constraints.
Where can I deploy Qdrant?
Qdrant supports multiple deployment options including fully managed cloud on AWS, Azure, and GCP, hybrid cloud with customer Kubernetes, private cloud for air-gapped deployments, and edge deployment for low-latency applications. It's designed to deploy anywhere from cloud to edge environments.
What programming languages and tools does Qdrant support?
Qdrant is built in Rust with SIMD optimization and includes a built-in web UI for collection exploration and query testing. It also provides native cloud inference for generating embeddings without requiring separate infrastructure.
What types of AI applications is Qdrant best suited for?
Qdrant is designed for RAG systems, AI agents, recommendation engines, semantic search applications, conversational AI chat, and custom chatbot builders. It's particularly useful for applications that need to handle high-dimensional vectors with complex filtering requirements.
