## Powerful primitives, seamlessly integrated

ComputeAIStorage & DatabasesMedia

### Deploy with one command

Build and deploy serverless functions and full-stack apps on Cloudflare's global network. No servers to manage. No cold starts or region complexity.

`npm create cloudflare@latest my-app`

[Create your first Worker](https://developers.cloudflare.com/workers/get-started/guide/)

### The AI inference platform

Run AI inference globally with one API call, build agents, and search across your data — no GPUs to manage, no capacity planning.

`npx wrangler ai models`

[Browse available models](https://developers.cloudflare.com/workers-ai/models/)
