Run Code That Writes Itself: Cloudflare Dynamic Workers
What if AI could write code to analyse your data — without ever seeing the data itself?
In this video we build a live report builder using Cloudflare Dynamic Workers. A natural-language prompt goes to Workers AI, the model writes a complete JavaScript Worker, and it executes immediately on Cloudflare's planetary network — no deploy step, no waiting. The survey data never leaves your infrastructure.
We cover:
→ How Workers AI generates a complete Worker from a plain-English prompt
→ How bindings give AI-generated code controlled access to your data
→ Why the Worker has no internet access by default — and what that means for safety
→ How saved reports stay live, load fast, and update automatically when data changes
→ The serverless cost model — you only pay for what you actually use
