Cloudflare Vibe SDK

Cloudflare Vibe SDK is a development toolkit for building, testing, and deploying AI-powered applications on Cloudflare’s global edge network. It provides a structured way to integrate large language models, embeddings, vector search, and other AI capabilities directly into applications running on Cloudflare Workers and Pages. The SDK offers high-level APIs for model invocation, prompt management, streaming responses, and handling context, allowing developers to focus on application logic rather than low-level infrastructure.

Key features include seamless integration with Cloudflare’s AI Gateway, support for multiple model providers, and utilities for managing tokens, rate limits, and observability. Developers can define AI workflows, chain model calls, and incorporate retrieval-augmented generation using vector indexes hosted on Cloudflare’s infrastructure. The SDK also supports TypeScript and modern JavaScript tooling, making it suitable for both greenfield projects and existing Cloudflare deployments.
