Workflow requires a publicly available API to send messages to. During development when applications are not yet deployed, developers typically need to expose their local API by creating a public tunnel. While local tunneling works seamlessly, it requires code changes between development and production environments and increase friction for developers. To simplify the development process, Upstash provides QStash CLI, which allows you to run a development server locally for testing and development.
With this work, the same UI that is given on the console.upstash.com can be used with local server(QStash CLI)
