VibeSDK
Cloudflare
Cloudflare has released VibeSDK, a full-stack, open source vibe coding platform that you can deploy with one click to host your own AI-powered application builder. The platform integrates LLMs (via an AI Gateway) to generate, debug, and iterate code in real time; provides isolated, secure sandboxes (or container-based environments) per user session for executing untrusted code; offers live previews and streaming logs to help users test and troubleshoot as they build; and uses workers for platforms to deploy each generated app at scale, with isolation between tenants. VibeSDK includes project templates, support for export to GitHub or a user’s Cloudflare account, cost and performance observability, caching for repeated requests, and multi-model support through routing across AI providers. It is designed to let teams offer internal or customer-facing “no-code/low-code” platforms, letting non-programmers spin up landing pages, prototypes, or applications from natural language prompts.Starting Price: Free -
