What Cloudflare VibeSDK is

Cloudflare VibeSDK is an open source reference implementation for AI application development on the Cloudflare Developer Platform. It takes a natural language requirement to a runnable edge application, connecting Workers, Pages, KV, Durable Objects, Queues, R2, Vectorize and AI Gateway.

Typical use cases given are intelligent customer service, retrieval-augmented generation and full-stack chat applications.
