Recommended route

For most teams

Start with the Agents Starter, add Sandbox only when the model must execute code, and bring in Workers for Platforms when the project needs to host multiple generated apps.

What is popular right now

VibeSDK is the most complete reference platform in this set, with roughly 5k stars.
Agents Starter is the cleanest default for chat-first agent hacks, with roughly 1.2k stars.
Sandbox SDK has nearly 1k stars and the strongest official examples for secure code execution.

Fast Start

The best official entry points

These are the highest-signal resources to put in front of hackathon teams first: one chat agent starter, two sandbox paths, one dynamic platform starter, and one full-stack generator.

Agents SDK

Agents Starter

Popular starter, 1.2k stars

The fastest path to a chat-based agent with Workers AI, tool calling, scheduling, vision, real-time sync, and a React UI.

Quick start

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

Streaming chat UIServer, client, and approval-based toolsScheduling, WebSockets, and persistent state

Sandbox SDK

Sandbox Minimal

Fastest sandbox starting point

A minimal Worker plus container setup for command execution, file operations, and secure code execution at the edge.

Quick start

npm create cloudflare@latest -- my-sandbox --template=cloudflare/sandbox-sdk/examples/minimal
cd my-sandbox
npm run dev

Command execution and file IODocker-backed local devIdeal base for code execution tools

Sandbox SDK

Workers AI Code Interpreter

Best AI plus code execution example

A polished template that combines Workers AI function calling with a Python execution environment inside Sandbox containers.

Quick start

npm create cloudflare@latest -- ai-interpreter --template=cloudflare/sandbox-sdk/examples/minimal
cd ai-interpreter
npm install
npm run dev

Workers AI plus Python tool callingNatural-language-to-code loopGreat fit for coding and analysis agents

Workers for Platforms

Worker Publisher

Platform starter kit

A reference platform that deploys isolated user Workers into a dispatch namespace and routes traffic by path.

Agents

Starter repo: 1.2k stars

Agents plus Agents SDK

Use this track when teams want stateful chat, long-lived agent identity, scheduling, approvals, WebSockets, and easy Workers AI integration.

Starter path: Start with cloudflare/agents-starter, then branch into MCP, callable methods, or Codemode once the base chat flow is working.

MCP

Official example-based path

Remote MCP Servers and Codemode

This is the highest-leverage extension path for hackathon teams that want agents to call structured tools or orchestrate many tool calls through code generation.

Starter path: Use the Agents MCP examples for server and client patterns, then layer Codemode when the model needs to write TypeScript to coordinate tool chains.

Sandboxes

SDK repo: 998 stars

Sandboxes plus Sandbox SDK

Pick this track when teams need secure execution, file systems, preview URLs, code interpreters, or agent-driven coding loops.

Starter path: Start with the minimal template, then jump to Code Interpreter, Analyze Data with AI, Claude Code, OpenAI Agents, or OpenCode examples.

Dynamic Workers

Cloudflare reference platform template

Workers for Platforms

Use this when hackathon teams need to deploy many generated or user-authored apps behind one platform with dynamic dispatch routing.

Starter path: Begin with the Worker Publisher template, then customize routing by path, subdomain, or KV and add per-user bindings or outbound worker controls.

VibeSDK

Repo: 5k stars, 1.2k forks

End-to-end app generation

VibeSDK is the most complete example in the stack: a production-grade text-to-app system built entirely on Cloudflare services.

Starter path: Use it when the team wants the whole architecture already composed: Agent, sandbox preview, data layer, and Workers for Platforms deployment.

Build Order

A simple path from agent to platform

This is the shortest path from prototype to something demoable on the public internet.

Start with an agent

Use the Agents Starter to get a real-time chat loop, tool calling, and state sync working in minutes.

Add secure execution

Bring in Sandbox when your agent needs to run code, inspect files, or host previews safely.

Host many outputs

Use Workers for Platforms when the hackathon project needs to deploy many generated or user-owned apps.

Use VibeSDK when you want the whole stack

Skip composition work and deploy the full app-generation platform when speed matters more than minimalism.
