VibeSDK

VibeSDK is Cloudflare's open-source platform where an AI agent builds and deploys full-stack apps on Cloudflare.

VibeSDK is an open-source agentic platform for building and deploying full-stack applications on Cloudflare, with a hosted trial at build.cloudflare.dev. A model-and-tool loop (Think) plans, edits files, deploys previews and inspects errors with the user in the loop, including structured clarifying questions. Each project gets an isolated Durable Object workspace. Dynamic Workers serve generated previews, Durable Object Facets give each app its own SQLite store, and Cloudflare Artifacts keeps git history and restore points. The live workspace shows files as they change, and the agent can read browser console output and redeploy in the same loop.
