What is it?

Cloudflare Experiments is an open-source monorepo of 60+ deployable Cloudflare Workers - each one a small, focused reference for a specific platform capability.

Not toy demos. Real patterns you can clone, run locally, deploy to the edge, and adapt for your own projects.

Why we built it

Cloudflare’s platform is powerful, but most getting-started content stops at “Hello World” and KV counters. Developers are left asking: What can I actually build with Workers AI, Browser Rendering, D1, R2, Durable Objects, or Queues?

This project answers that with one experiment per capability - each with docs, tests, and a Deploy button.

What you get

• 60+ experiments across AI, scraping, browser automation, storage, networking, and async workflows

• One-click deploy per experiment via Cloudflare Deploy buttons

• Full documentation at cloudflare-experiments.com

• Consistent structure - same layout, TypeScript, Vitest tests, wrangler.json in every experiment

• MIT licensed - fork freely

Featured examples

• AI Website Summary - summarize any URL with Workers AI

• Screenshot API - PNG captures via Browser Rendering

• RAG Mini Search - Vectorize + Workers AI grounded Q&A

• Link Shortener - D1 + KV pattern

• Uptime Monitor Alerts - Cron + D1 + email alerts

• Social Preview Inspector - validate OG/Twitter/Google snippets

Who it’s for

• Developers evaluating or learning the Cloudflare platform

• Teams looking for copy-paste patterns before building production Workers

• Anyone tired of piecing together docs from scattered blog posts
