Need to show off your work? LocalTunnel gives you instant, global access in Termux.
I remember the first time I needed to share a project with a collaborator while working remotely. I had been developing a small web app on my local machine, and suddenly, I realized the need to give someone access to test it. Setting up a public-facing server or a cloud service seemed overkill for a simple demo.
That’s when I discovered LocalTunnel. It was like a magic trick—within minutes, I had a public URL to share with anyone, all through Termux on my phone. No complicated configurations, no need for a dedicated server—just the simplicity of a local tunnel that brought the project to life for others to see.
If you’ve ever struggled with sharing your local dev projects, LocalTunnel is about to become your best friend. Ready to make it work for you? Keep reading to see how.

localtunnel in Termux Use Cases
- Testing Webhooks: When developing applications that rely on webhooks, you can use localtunnel to expose your local development server to the internet, allowing external services to communicate with it.
- Client Demos: Share a working prototype with clients or colleagues without needing to deploy it to a public server, making quick feedback and iterations possible.
- Collaborative Development: Enable team members to access your development environment for real-time feedback or joint problem-solving sessions.
- Remote Debugging: Grant access to a remote developer or support person to debug issues on your local server.
- IoT Device Integration: Use localtunnel to expose the web interface of your local IoT devices, making them accessible from anywhere in the world for remote control and monitoring.

Understanding the Prerequisites and Initial Setup
Before diving into using LocalTunnel with Termux, it’s important to make sure your environment is ready. Termux itself is a terminal emulator for Android, which provides a Linux-like environment, but it doesn’t come pre-installed with all the necessary tools. To get started, you’ll need to install Termux from the Google Play Store (or F-Droid for the open-source version).
Once Termux is installed, you will need to set up the basic development environment by installing essential packages. For instance, if you’re using LocalTunnel in conjunction with Node.js, you’ll need to install Node.js in Termux first.
To install Node.js in Termux, run the following command:
pkg install nodejsNext, you’ll install LocalTunnel via npm, which is Node’s package manager. The command is:
npm install -g localtunnelWith these tools in place, you’re now set to use LocalTunnel to expose your local server to the world, providing access even when you’re working behind a firewall or NAT (Network Address Translation).
Option: Install localtunnel Globally
With Node.js installed, you can now install localtunnel globally using npm (Node Package Manager).
Install localtunnel:
npm install -g localtunnelVerify the installation:
lt --versionThis command will display the installed version of localtunnel, confirming that it’s ready to use.
Start Your Local Web Server
Before you can share your server with the world, you need to ensure it’s running locally. Here’s an example using Python’s built-in HTTP server:
Navigate to your web project directory:
cd /path/to/your/web/projectStart the server (replace 8000 with your desired port):
python3 -m http.server 8000Your web server is now running locally on port 8000.
Expose Your Local Server to the Internet Using localtunnel
Now that your server is running locally, you can expose it to the internet using localtunnel.
Run localtunnel and specify the port your server is using:
lt --port 8000 localtunnel will generate a URL that redirects traffic to your local server. Copy this URL and share it with anyone who needs access.
Custom Subdomain (Optional)
If you prefer a custom subdomain for your server, localtunnel allows you to specify one. This is particularly useful for branding or easy recall.
Use the --subdomain flag:
lt --port 8000 --subdomain yourcustomnameAccess your server: If available, your server will be accessible at yourcustomname.loca.lt.

Security Considerations and Risks
Using LocalTunnel to expose your local web server comes with inherent risks. While LocalTunnel provides convenience for sharing your development projects, it opens up your local server to the public, which can expose sensitive information or vulnerabilities. Here’s what to consider:
- Limited Access Control: By default, LocalTunnel generates a subdomain URL that anyone can access. If you’re working with sensitive data, make sure the tunnel is not publicly accessible or expose only specific endpoints.
- Potential for Data Leakage: Exposing your local server might allow malicious actors to interact with it. Always ensure that any exposed service is behind secure authentication and that no sensitive data is exposed to the public.
- Man-in-the-Middle (MITM) Attacks: While LocalTunnel uses encryption, your traffic could still be intercepted if LocalTunnel’s server is compromised or if you’re not using HTTPS for your local server.
To mitigate these risks, you should:
- Use HTTPS for any services you expose.
- Limit access to your tunnel by requiring authentication (e.g., basic auth, OAuth, etc.).
- Avoid using LocalTunnel for production services that contain sensitive data.

Alternative Solutions and Use Cases
While LocalTunnel is a great tool for quickly exposing local services, it’s not the only option available. Some other tools, like Ngrok, serve similar purposes, but with additional features such as password protection and custom subdomains. Here’s a brief comparison to help you decide which one works best for your needs:
- Ngrok: Ngrok offers a secure way to expose your local machine to the internet, with options for custom subdomains and password protection. It’s widely used for testing APIs, webhooks, and applications. However, while Ngrok has a free tier, its premium version offers more advanced features like persistent URLs and more tunnels.
- SSH Tunneling: For more advanced users who prefer to have complete control over their environment, SSH tunneling can be a better option. It requires more setup but offers a more robust, secure solution for port forwarding without relying on third-party services.
Use cases for LocalTunnel include:
- Testing APIs or webhooks by providing remote access to your local server.
- Demonstrating your work to clients or colleagues quickly without deploying it to production.
- Sharing unfinished or experimental web projects with others for feedback.
By exploring these alternatives and understanding the potential trade-offs, you can decide which tool works best for your workflow.

Troubleshooting Tips
- Port in Use: If you encounter an error indicating that the port is already in use, stop any other services running on the same port or choose a different one.
- Connection Issues: Ensure your internet connection is stable. If you’re using mobile data, check if any firewall or restrictions are applied by your carrier.
