## What it is
The Cloudflare Workers SDK is a monorepo containing Wrangler, the official CLI for building, testing, and deploying Cloudflare Workers serverless applications, along with supporting packages like create-cloudflare. It provides commands for local development, secret management, database provisioning, and deployment to Cloudflare's global edge network.

## Use cases
- deploy a serverless API to Cloudflare Workers from the command line
- run and debug Workers locally during development
- create a new Cloudflare Workers project from a template
- manage secrets and environment variables for Workers
- provision and query D1, KV, and R2 storage via CLI
- schedule cron jobs and deploy background workflows

## When to choose
- you are building or deploying applications on Cloudflare Workers
- you want a single CLI for local dev, testing, and edge deployment
- you need to manage Cloudflare developer platform resources (D1, KV, R2, Queues) from the terminal
- you want to scaffold full-stack apps on Cloudflare's edge network

## When to avoid
- you deploy to AWS, GCP, Azure, or other non-Cloudflare platforms
- you need a general-purpose serverless framework not tied to Cloudflare
- you only want the Workers runtime without tooling
