Access Your Localhost From Anywhere: A Developer's Guide to Secure Tunneling

You've painstakingly crafted a website design on your local machine, complete with sample content. Now, you need to test it on various mobile devices and share it with clients – without the hassle of deploying it to a public server prematurely. This guide explores several tools that create a secure tunnel from the internet to your localhost, allowing remote access and streamlined testing.

This article covers: ngrok, PageKite, localtunnel, boringproxy, and BrowserStack.

Key Advantages:

1. Streamlined Workflows: Secure tunnel services simplify testing on various devices and client collaboration without premature public deployment.
2. Diverse Tool Options: Each tool offers unique features catering to different development needs, from traffic inspection to multi-platform hosting.
3. Enhanced Testing and Accessibility: Features like traffic inspection, custom domains, and password protection create a robust testing environment and facilitate easy client demonstrations.

How it Works:

Secure tunnel services establish a connection between the internet and your local machine. A public URL is provided; incoming requests to this URL are forwarded to your localhost server. The complex setup is handled automatically; you simply install the application and point it to your localhost.

Important Note on Virtual Hosts:

If you use virtual hosts, ensure the public URL provided by the tunneling service is added as a ServerAlias in your httpd.conf file (or equivalent configuration file for your web server). For example:

<code><virtualhost>
    DocumentRoot "/Users/patcat/Web"
    ServerName mytestsite.test
    ServerAlias 350c0f8e.ngrok.com
</virtualhost></code>

ngrok:

ngrok (available for Windows, macOS, and Linux) creates a tunnel and allows traffic inspection and replay for testing. Basic features are free; advanced features (custom subdomains, reserved domains) require a paid plan. ngrok's key advantage is its lack of dependencies.

Using ngrok:

1. Download ngrok from ngrok.com.
2. Open your terminal, navigate to the ngrok directory, and run: ./ngrok http 80
3. Access your localhost via the provided ngrok URL (e.g., http://42e474ef9799.ngrok.com).

ngrok's traffic inspector (accessible at http://localhost:4040/) allows you to analyze past requests.

ngrok Advanced Features:

• Password protection: ngrok http -auth="username:password" 80
• Custom subdomains (paid plan): ngrok http -subdomain nogophersinmytunnel 80
• Custom domains (paid plan): ngrok http -hostname="tunnel.yourdomain.com" 80
• Tunneling to IP addresses: ngrok http 192.168.0.27:80
• Non-HTTP services: ngrok tcp 22

PageKite:

PageKite (Python-based, supports Windows, macOS, Linux, and Android) is a robust, long-standing alternative to ngrok. It offers a free trial, followed by a pay-what-you-want model. It includes a built-in firewall blocking common attack vectors.

Using PageKite:

1. Download PageKite from PageKite.net.
2. Run: pagekite.py 80 hurrygetintothefancytunnel.pagekite.me (replace with your chosen subdomain).

PageKite Advanced Features:

• Built-in web server for static files: pagekite.py /path/to/folder igotthattunnelvision.pagekite.me
• Password protection: pagekite.py 80 terelekkayatuneli.pagekite.me password/username=password
• IP address restriction: pagekite.py 80 arcadefirecamethroughmywindow.pagekite.me ip/1.2.3.4=ok ip/4.5.6=ok

localtunnel:

localtunnel (Node.js, Go, and C#/.NET clients) is a straightforward tunneling service.

Using localtunnel:

1. Install globally: npm install -g localtunnel
2. Run: lt --port 80

localtunnel Advanced Features:

• Custom subdomains: lt --port 80 --subdomain platypusestunneltoo
• Node.js API for automated testing.

boringproxy:

boringproxy is a free, open-source (MIT license) option, primarily focused on self-hosting. It's available as a single executable for Linux and Windows (macOS support is untested).

BrowserStack:

BrowserStack offers virtual machines and browser testing capabilities. While it doesn't directly expose your localhost, its browser extension facilitates access via their servers (paid service).

Conclusion:

Numerous tools simplify accessing your localhost remotely. ngrok and PageKite stand out for their ease of use and comprehensive features. Choose the tool that best suits your needs and security requirements. Remember to prioritize security when exposing your localhost to the internet.
