Cloud//Cloudflare//Vectorize

Cloudflare's edge-native vector database. A separate product from D1 — D1 is SQLite and doesn't have vector extensions natively.

Cloudflare's edge-native vector database. A separate product from D1 — D1 is SQLite and doesn't have vector extensions natively.

Stores embeddings and performs cosine similarity search at the edge

Up to 5M vectors per index, 50K namespaces per account

Integrates with Workers and Workers AI for inference → embed → store → search, all on Cloudflare

Limitation: no hybrid search (BM25 + vectors in one query). For that you'd need D1 (FTS5 full-text search) + Vectorize together — two products for what Weaviate does in one.

The Cloudflare answer to pgvector: instead of adding vectors to your SQL database, it's a dedicated vector service alongside your SQL database
