Step-by-Step Procedure to Set Up TryCloudflare to Access Your Local Application Over the Internet

Developers often need to access their locally running applications over the internet during development and testing. Whether you are building a new web app or troubleshooting issues in an existing one, having the ability to easily share your local environment with team members and testers is invaluable.

Traditionally, publishing a locally running app on the public internet required configuring port forwarding on your router or using tunneling software like ngrok. These options can be complex to set up and often come with limitations.

In this post, we’ll explore how to leverage Cloudflare’s TryCloudflare service to seamlessly Set Up TryCloudflare to Access Your Local Application Over the Internet. With just a few commands, you can instantly Make private site public using cloudflared. Read on to learn how to easily Host a localhost service on the internet using TryCloudflare.

What is Required to Host a Localhost Service on the Internet?

In general, publishing a locally running web server on the public internet requires:

Setting all this up requires networking expertise and control over infrastructure like routers and DNS records. The process differs across operating systems and network configurations. Maintenance like certificate renewals adds overhead.

Tools like ngrok simplify aspects of this process through their tunneling and orchestration capabilities. But they come with restrictions on usage, features, and traffic volumes in their free tiers.

This highlights the need for a frictionless way to Host a localhost service on the internet using TryCloudflare that abstracts away these complexities and limitations.

What is TryCloudflare?

TryCloudflare is a service from Cloudflare that provides free, instant, and unlimited public access to web servers and sites running on your local machine.

With just a single command, TryCloudflare will spin up a Cloudflare Tunnel to your localhost and generate a random public subdomain on the trycloudflare.com domain. Traffic to this auto-generated subdomain is seamlessly routed through Cloudflare’s network to your local web server.

Some key capabilities provided by TryCloudflare include:

In summary, TryCloudflare simplifies the process of Publish local projects with cloudflared by handling all the complex networking and security requirements for you.

How Does TryCloudflare Work?

Under the hood, TryCloudflare relies on two Cloudflare technologies: Cloudflare Tunnel and the Cloudflare virtual network.

The Cloudflare Tunnel client (cloudflared) runs locally on your machine as a daemon or service. When you invoke TryCloudflare, cloudflared will establish an outbound-only connection from your machine to the nearest Cloudflare data center.

This creates a secure Tunnel that encapsulates traffic and hands it off to Cloudflare’s network. No incoming ports need to be opened on your local firewall. cloudflared registers the Tunnel with a randomly generated UUID subdomain under trycloudflare.com.

Inside the Cloudflare network, incoming requests addressed to this subdomain are routed through the Tunnel to your origin web server running locally. As traffic leaves Cloudflare to your machine, it passes through the Cloudflare Web Application Firewall for inspection. This protects your local machine from web-based attacks.
