Cloudflare Vectorize

Serverless vector DB on Workers

Free tier + paidSearch, vector & RAGdevelopers.cloudflare.com

What it is

Cloudflare's vector database, queried from a Worker with no network hop or over an HTTP API. Billing is purely by vector dimensions stored and queried — no CPU, memory, active index hours, index count or data transfer charges, and empty indexes cost nothing at all.

Why it earns a slot

If the app already lives on Cloudflare this is the vector store with zero added latency and near-zero idle cost. Workers AI can generate the embeddings inside the same request.

Know before you commit

Dimension-based billing misleads — 1M vectors at 768 dimensions is 768M dimensions, far past the free allowance. Query and filter features are thinner than Qdrant or Weaviate.

Getting started

npx wrangler vectorize create my-index --dimensions=768 --metric=cosine
