# Cloudflare

Challenge guidance, participant resources, opening materials, and judging requirements for Cloudflare Hack Days.

**Last reviewed:** August 2026

Cloudflare supports Major League Hacking and the Hack Days program with a unified platform for application and AI compute. Hackers can use Workers to build, deploy, and run applications and Workers AI to add AI inference without splitting their project across multiple infrastructure tools.

## Best Use of Cloudflare

Your idea should not need five different platforms before anyone can try it. Use Cloudflare Workers and Workers AI to take an AI-powered application from code to deployment on one unified platform. So, what can you build with Cloudflare?

* Run your application's logic with Workers and deploy it on Cloudflare's global network
* Add serverless AI inference with Workers AI to create assistants, generators, classifiers, and other intelligent experiences
* Combine application code, APIs, and AI on one developer platform instead of splitting deployment and infrastructure across multiple tools

Move from an idea to a live AI application… what will you build with Cloudflare today?

## Participant Resources

Share these resources before and during the event:

* [Cloudflare Workers overview](https://developers.cloudflare.com/workers/)
* [Build your first Worker](https://developers.cloudflare.com/workers/get-started/guide/)
* [Workers AI overview](https://developers.cloudflare.com/workers-ai/)
* [Get started with Workers AI](https://developers.cloudflare.com/workers-ai/get-started/)
* [Explore Workers AI models](https://developers.cloudflare.com/workers-ai/models/)
* [Try the Workers AI Playground](https://playground.ai.cloudflare.com/)

Encourage hackers to start by deploying a Worker, then add a model through Workers AI and test it in a working application. The Workers AI Playground can help them explore models before choosing one.

## Opening Ceremony

Use the opening ceremony materials included in your event onboarding.

## Judging Evidence

Confirm that the winning project is deployed with Cloudflare Workers and uses Workers AI for a meaningful part of the experience. Ask the team to identify its Worker and model integration in the README, then show the deployed application and relevant code or configuration during the demo.

## Expected Prize

Prize details will be included in your event's onboarding materials. Check them before sharing prize information with participants.
