Cloudflare has open sourced VibeSDK to let developers build and deploy AI-powered applications with natural language prompts, aiming to accelerate innovation and scale vibe coding worldwide.
Cloudflare has announced the open-sourcing of VibeSDK, a move designed to democratise AI-powered software development by enabling developers to create their own vibe coding platforms in a single click.
VibeSDK allows developers to build, test and deploy applications simply by describing them in plain language. It integrates large language models (LLMs) for code generation, debugging, and real-time iteration, while running securely inside Cloudflare-powered sandboxes.
The framework automates the entire workflow—generating files, installing dependencies, starting servers, and providing instant preview links. Developers can also accelerate common use cases with pre-built templates, including React apps and APIs.
Applications are deployed globally on Cloudflare Workers for Platforms, ensuring scalability with isolated environments for each app. Built-in observability and cost tracking further enhance efficiency. Through Cloudflare’s AI Gateway, VibeSDK routes requests across multiple model providers such as Google’s Gemini, caches popular responses to reduce costs, and feeds logs and errors back to the LLM for live debugging loops.
VibeSDK also offers flexibility, allowing projects to be exported to GitHub or directly to a developer’s Cloudflare account, making it suitable both for companies embedding AI coding tools into their products and for teams seeking secure, internal app-building platforms.
Cloudflare noted that this approach mirrors its earlier decision to open-source the Workers runtime, providing a reference architecture to accelerate innovation.
