Email Agent Workshop

Workshop: Build an AI email agent with Cloudflare Agents SDK and Email Routing.

React + Vite + Hono + Cloudflare Workers

This template provides a minimal setup for building a React application with TypeScript and Vite, designed to run on Cloudflare Workers. It features hot module replacement, ESLint integration, and the flexibility of Workers deployments.

demoscene is a Cloudflare Worker that scans a curated set of GitHub accounts and publishes a reverse-chronological feed of public Cloudflare projects from the Cloudflare DevRel team.

It discovers repositories with the GitHub API, detects top-level Wrangler configs, stores the first README it sees, derives a cleaned preview for cards, and renders the result as HTML, JSON, and RSS.

Cloudflare Queue + Anthropic Batch API demo

A tiny Cloudflare Worker that takes user feedback over HTTP, drops it on a Cloudflare Queue, and uses the consumer batch to create a single Anthropic Message Batch job. A cron trigger polls Anthropic for results and writes them back to D1.
