Promptly

Promptly is a Cloudflare Workers app for storing educational AI prompts by slug and presenting them one sentence at a time. It is designed for talks, workshops, and demos where you want to teach a prompt sentence-by-sentence and let the audience take the prompt away.

Pickled

A real-time multiplayer pickleball game built on Cloudflare Workers. Players use their phones as motion controllers to volley a virtual pickleball back and forth on a shared screen.

Y

An internal social-media scheduling tool for the @CloudflareDev X account, built by Cloudflare DevRel. (It schedules for X - so naturally it's called Y.)

Turn a list of links into an AI-generated audio podcast.

The backend Worker fetches each page, writes one spoken-word script with Workers AI, narrates it with Deepgram Aura, and stores the finished MP3 in R2. The web app provides a simple Dropcast UI for generating and listening to episodes.

Pixel Shading Reference

A small React + TypeScript reference tool for studying pixel-art lighting on simple forms.

Build Email-Native Agents — talk deck

Conference-talk slide deck (Vite + React + Framer Motion + Tailwind), deployed to Cloudflare Workers as static assets.

🍃 Leaflet

A simple blog app built with Astro, Hono, and SQLite. Username-only auth, draft/publish workflows, and comments.

An personal chat agent built on Cloudflare Think. It uses Apify Actors via the Apify MCP server to fetch real web data on demand — the agent pays for web data to get things done.

Uses Workers AI (no API key required), with the Apify MCP server auto-connected on startup and tools for task scheduling. The agent remembers facts about the user across turns via Think's context blocks, and supports vision (image input).

jilles-game-sprites

A pipeline that turns a selfie into a game-ready character sprite sheet, keeping the original poses and grid alignment intact.

Phaser × Cloudflare Workers Starter

Build real-time browser games with Phaser 4, Cloudflare Workers, and Durable Objects.

This is a minimal Cloudflare virtual try-on demo built with Next.js + vinext.

It uploads a person image and garment reference images to R2 via Cloudflare bindings, calls pruna/p-image-try-on through the Workers AI binding with the p-image-try-on-demo AI Gateway, then shows the generated image.

402 MCP — Restaurant Finder with Paid Tools
