Cloudflare launch pad for hackathon teams

Choose a path. Run a starter. Ship the demo.

Set up your coding agent with live Cloudflare context, decide what you are building, and land on a starter that can run locally and deploy to the public edge.

Set up your agent Choose a build path Create an account

Step 01 / Set up your coding agent

Give your agent live Cloudflare context first.

Cloudflare Skills gives coding agents current product guidance, Wrangler workflows, and access to Cloudflare MCP tools before the hack starts.

Step 02 / Choose a path

Start from the thing you need to ship.

Every branch ends at a runnable starter. Pick the smallest path that proves the hackathon idea, then add platform primitives only when the demo needs them.

What are you building?

AAn application

Workers hosts the UI, APIs, state, data, and background work.

Website or full-stack appReact on Workers→ API or backendOpenAPI plus Hono→ Relational dataD1 application→ Real-time rooms or coordinationDurable Chat→ Long-running background workWorkflows→ Customers deploy codeWorker Publisher→

BAn agent

Start with Flue. Branch only when the harness or runtime requirement says otherwise.

New autonomous agentFlue 2.1 and the Pi harness→ No Pi or need lower-level primitivesCloudflare Agents SDK→ Run Codex or another coding harnessCloudflare Sandbox→ Execute generated code safelyCode Interpreter→ Generate and host complete appsVibeSDK→

Step 03A / Agent starters

Start with Flue. Keep the escape hatches visible.

Flue is the default for a new autonomous agent. Agents SDK and Sandbox cover lower-level Cloudflare runtime control and non-Pi coding harnesses.

Default agent path

Recommended

Flue 2.1 on Cloudflare

Build autonomous TypeScript agents with a hooks-based harness, Pi model providers, durable conversations, skills, tools, subagents, channels, and optional sandboxes on Workers.

Quick start

npx @flue/cli@2.1.0 init my-agent --target cloudflare
cd my-agent
npm install
npm run check:types
npm run dev
npm run deploy

Agent hooksPi harnessDurable ObjectsSkillsCloudflare target

Choose this first for a new autonomous agent unless you need a non-Pi harness or lower-level Agents SDK primitives.
Requires Node.js 22.19 or newer. Add provider credentials, or use a cloudflare/* model through Workers AI.

Getting started Cloudflare guide GitHub

Cloudflare Agents SDK

No Pi

Agents Starter

Use the lower-level Cloudflare agent runtime for AI SDK models, synchronized state, callable RPC, scheduling, Workflows, WebSockets, approval tools, Voice, Browser Run, and custom Durable Object lifecycle behavior.

Quick start

npm create cloudflare@latest -- --template cloudflare/agents-starter
cd agents-starter
npm install
npm run dev
npm run deploy

AI SDKReactState syncTool approvalsWorkers AI

Choose this when Flue's Pi harness is not the right execution model or your app needs Agents SDK-specific runtime controls.
Local Workers AI use requires Cloudflare authentication.

Codex App Server in Sandbox

Run OpenAI Codex in an isolated Cloudflare Sandbox with a streaming browser UI, WebSocket middleware, deny-by-default egress, and credential injection outside the container.

Quick start

git clone --depth 1 https://github.com/cloudflare/sandbox-sdk
cd sandbox-sdk/examples/codex-app-server
cp .dev.vars.example .dev.vars
npm install
npm run dev
npm run deploy

Workers AI Code Interpreter

Pair Workers AI tool calling with a Python execution environment for analysis, generated code, and file-backed tasks without adopting a full coding-agent harness.

Quick start

cd sandbox-sdk/examples/code-interpreter

Generated-app platform

Full platform

VibeSDK

Deploy a complete text-to-app platform built around Think, project Durable Objects, Cloudflare Artifacts, Dynamic Workers, Facets, and AI Gateway.

ThinkArtifactsDynamic WorkersAI GatewayApp generation

Best when a team wants the composed platform rather than individual agent and deployment primitives.

Deploy VibeSDK Live demo GitHub

Step 03B / App starters

Use the platform primitive that matches the demo.

These starters cover the common hackathon shapes without forcing every team into the same architecture.

Start a Vite-powered React application with Worker-side APIs and a production deployment path in one project.
