wrangler
Advanced tools
wrangler is a command line tool for building Cloudflare Workers.
To get started quickly with a Hello World worker, run the command below:
npx wrangler init my-worker -y
For more info, visit our Getting Started guide.
We support running the Wrangler CLI with the Current, Active, and Maintenance versions of Node.js. Your Worker will always be executed in workerd, the open source Cloudflare Workers runtime.
Wrangler is only supported on macOS 13.5+, Windows 11, and Linux distros that support glib 2.35. This follows workerd's OS support policy.

Wrangler is configured via a wrangler.toml or wrangler.json file in the project root. An example configuration generated by npx wrangler init or npx create cloudflare is as follows:
name = "my-worker"
main = "./src/index.ts"
compatibility_date = "YYYY-MM-DD"

The Serverless Framework is a popular open-source framework for building and deploying serverless applications across various cloud providers, including AWS, Azure, and Google Cloud. It offers a broader range of integrations and features compared to wrangler, which is specific to Cloudflare Workers.
Architect (or @architect) is an open-source framework for building and deploying serverless applications on AWS. It provides a simple and declarative way to define serverless infrastructure and focuses on developer productivity. Unlike wrangler, which is Cloudflare-specific, Architect is designed for AWS.
Claudia.js is a tool for deploying Node.js projects to AWS Lambda and API Gateway. It automates many of the deployment steps and simplifies the process of creating and managing serverless applications on AWS. Claudia.js is more AWS-centric, whereas wrangler is tailored for Cloudflare Workers.
