Cloudflare Wrangler is the official command-line interface (CLI) tool designed for building, managing, and deploying applications on Cloudflare’s developer platform. Think of it as the main bridge between your local development environment and Cloudflare’s global network, letting you seamlessly interact with all of Cloudflare’s serverless products. As part of the broader Cloudflare Workers SDK, Wrangler works hand-in-hand with create-cloudflare (C3) project scaffolding tool and Miniflare local simulator to create a complete and efficient development toolchain.
