Four AI Demos on Cloudflare's Free Tier: How We Built Them
We built four working AI demos (document Q&A, invoice reading, quote drafting, and a shop assistant) on Cloudflare Workers, Workers AI, Durable Objects, Workflows, D1, and AI Search, all inside the free allowances. The architecture, the measured cost of each request, and what we learned.
Cloudflare Security Best Practices for AI Apps
The security practices we follow when we put AI on Cloudflare Workers: server-only session state, a budget in front of every model call, safe handling of uploads and saved results, rate limiting at two levels, and the seven layers between the internet and a model call. Written with a focus on keeping the bill under control.
