Welcome to the Cloudflare Developers YouTube channel! Here you will find tutorials created by Cloudflare developers, to help all ...
Claude in the Box - Use Anthropic Agent SDK in a Sandbox
The video shows how to run and host an Anthropic-style agent locally using a Cloudflare sandbox, enabling autonomous, code-driven agents with skills and external tools. The creator walks through setting up the sandbox, wiring environment variables, and building extensible skills (like markdown fetching and tutorial analysis) to review tutorials and generate actionable feedback, ultimately highlighting exciting QA possibilities by running tutorials inside a sandbox.
Deploy TanStack Start on Cloudflare Workers in 10 mins
The video demonstrates how to build and deploy a TenStack Start (TanStack Start) application on Cloudflare Workers, including creating a new project with the Cloudflare setup, deploying an existing app, and wiring in various Cloudflare bindings (D1, R2, KV, etc.). It covers local development, SSR/server functions, and deployment workflows using Wrangler, the V plugin, and the necessary config files, plus how to test and preview before going live.
Make Your Website Smart: Add AI Search with NLWeb in 10 Minutes — No Coding Needed!
The video demonstrates how to create a ready-made RAG (retrieval-augmented generation) pipeline for any website in under 10 minutes using NL Web and Cloudflare, highlighting a one-click deployment that handles indexing, embeddings, vector storage, and an MCP server for AI agents. It walks through integrating a chat interface powered by the site’s own content, embedding a widget, and using an open-source stack to enable both AI agents and humans to safely access and query the site content, with a live demo on the creator’s blog and personal site.
What is Vibe Coding? | Vibe Coding with Catherine and Harshil
A duo demonstrations for a vibe coding series, where Harshel and Katherine introduce wipe coding, share personal experiences, and explore building apps with Cloudflare tools and Windsurf, including a live Flappy Bird prototype and a discussion on debugging with AI.
Build a Voice Based Image Editor with Replicate, Deepgram, and Agents SDK
The speaker demonstrates building a real-time, cloud-powered app by stitching Replicate models, image editing tools, and Cloudflare primitives into a scalable workflow. They walk through prompt-driven image generation, editing via an agent with RPC and state syncing, voice input via Deepgram, and storing results in Cloudflare R2, all while exploring future features like user interactions (likes) and dynamic agents.
Build Real-Time Video Apps in Minutes with Cloudflare RealtimeKit
The video introduces Cloudflare Realtime Kit, a set of web and mobile SDKs that abstract WebRTC complexity to help you build real-time video apps quickly. It covers how RTK handles sessions, media, signaling, and connectivity (with tokens, presets, roles, and an SFU), showcases templates and UI components, and walks through a Lenley virtual classroom demo including backend, frontend, customization, analytics, and how to deploy via a Cloudflare worker or dashboard.
Chatting Agents SDKs with Cloudflare, Anthropic, and OpenAI (Panel)
The talk reviews the year of agent development, introduces a growing team, and outlines a forward roadmap focused on code mode, runtime flexibility, and open ecosystems to empower developers building AI agents across platforms.
Vibe coding with Windsurf | Vibe Coding with Catherine and Harshil
The video covers hands-on live coding with Wind Surf and Cloudflare tools, showing how to bootstrap a Cloudflare app, explore AI assisted coding, and plan an event automation flow using Luma and webhooks. It also discusses model selection, API security, and steps to avoid building everything at once by breaking tasks into manageable parts.
Next.js on Cloudflare: Deploy to the Edge with a Single git push
The video walks through bootstrapping a Next.js app and deploying it to Cloudflare’s edge with Openext, using a simple get-push workflow, preview deployments, and GitHub deployment wiring. It then demonstrates adding middleware to read Cloudflare context (like country data) and modify request headers, showcasing a fast, end-to-end developer experience on Cloudflare’s edge, including workflow details and the free plan viability.
Give Your LLM a Sandbox: Introducing Dynamic Isolated Workers
The video introduces MCP code mode, a reliable, code-based alternative to traditional multi-step tool calls for LLMs, implemented in a secure sandbox. It then dives into the dynamic worker loader API, showing how to spin up isolated worker contexts on the fly, customize internet access via proxy functions, and pass secure capabilities through bindings, all demonstrated with practical examples and setup guidance.

FLUX.2[dev] is AWESOME on Cloudflare Workers AI
The video introduces Flux 2 in Workers AI, highlighting its enhanced photorealism, character consistency with multi-reference inputs, and hands-on demos comparing Flux 1 and Flux 2, plus resources to get started.
Globally Fast Applications with Cloudflare Hyperdrive and PlanetScale
A hands-on demo showing how Hyperdrive with PlanetScale and Cloudflare can dramatically reduce latency for a global Next.js app. The video walks through creating a regional PlanetScale database, wiring it to a Next.js app, deploying with Hyperdrive, and enabling caching to achieve near-instant responses, then compares performance with and without caching across planetary-scale deployment.
