Qdrant

As vector databases go, Qdrant is the open-source one written in Rust, a language chosen for reliability and performance.

Qdrant is a vector database and similarity search engine that gives AI applications fast semantic search through a convenient API.

Qdrant works with a range of embeddings and frameworks, so you can add it to the stack you already run instead of rebuilding around it.

For production, Qdrant offers cloud-native scalability and high availability, plus storage options with built-in compression to keep costs down.

Its makers say thousands of AI solutions use it.

Running a vector database takes technical skill, so Qdrant suits developers and engineering teams far more than general office users.

Pricing follows an enterprise model, which means you will likely need to talk to the team before you know what larger deployments cost.
