Cloudflare Wrangler

Wrangler is the official command-line interface (CLI) tool designed for developers to build, test, and deploy applications on the Cloudflare Workers platform. Originally developed to facilitate the use of Rust in webassembly environments, it has since evolved into a comprehensive tool supporting JavaScript, TypeScript, and various other assets within the Cloudflare ecosystem.

The tool was created by Cloudflare, Inc., an American web infrastructure and security company. As a software product, its 'manufacturing' or development primarily takes place within the United States, though it is distributed globally via digital package managers like npm. Cloudflare remains the sole owner and developer of the project, maintaining it as an open-source tool to empower their edge computing community.
