Local website testing allows developers to test their websites locally, either manually or automatically. Once the developer and QA team ensure the website functions correctly locally, it is pushed to a production environment.

Digital experience testing platforms like LambdaTest enables developers and the QA team to [test in local environments](https://www.lambdatest.com/test-in-local-environments?utm_source=devto&utm_medium=organic&utm_campaign=may22_kj&utm_term=kj&utm_content=webpage) by providing remote access to real browsers and operating systems without the need for complex local test environments.

To further enhance your local testing experience, we are introducing [LambdaTest Tunnel Docker Extension](https://hub.docker.com/r/lambdatest/tunnel?utm_source=devto&utm_medium=organic&utm_campaign=may22_kj&utm_term=kj&utm_content=webpage), which allows you to perform [cross browser testing](https://www.lambdatest.com/online-browser-testing?utm_source=devto&utm_medium=organic&utm_campaign=may22_kj&utm_term=kj&utm_content=webpage) of locally hosted websites and web applications across 3000+ browser and OS environments, eliminating the need to launch the tunnel through the CLI manually.

## What is LambdaTest Tunnel Docker Extension?

Docker Extensions help you develop and integrate software applications into your existing workflows. With LambdaTest Tunnel as a Docker Extension, you can run local tests across an [online device farm](https://www.lambdatest.com/online-device-farm?utm_source=devto&utm_medium=organic&utm_campaign=may22_kj&utm_term=kj&utm_content=webpage) of 3000+ real browsers, devices, and OS combinations, without launching the tunnel from the command line interface.

Let’s see how this Docker extension helps you:

* **Hassle-Free Setup**: It makes it easy to set up the LambdaTest tunnel in a single click without requiring it to launch from the CLI.

* **Secure SSH Tunnel**: The LambdaTest Tunnel Docker extension provides a secure tunnel between your local machine and the LambdaTest cloud servers. This ensures your data is protected during testing.

* **Access to Large Browser Farm**: With the LambdaTest Tunnel Docker extension, you can test your websites and web applications on various browser and operating system combinations without setting up your test infrastructure.

* **Advanced Configurations**: LambdaTest Tunnel Docker Extension helps you leverage advanced tunnel features like Proxy Port, Environment, Local File Server Directory, Info API Ports, and more.

## Why use LambdaTest Tunnel Docker Extension?

Testing a website, especially in a production environment, can be time-consuming and resource-intensive. This leads to a slower development process and makes it more challenging to identify and address issues early, thereby delaying developer feedback.

That’s why developers and QAs test websites and web apps beforehand to debug quickly and fix obvious bugs in their code. By running tests locally, developers can get faster feedback on their code commits, enabling them to make changes and improvements more quickly, improving the overall development process.

However, QA teams can leverage the true potential of local testing using LambdaTest Tunnel Docker Extension on a cloud-based infrastructure. Devs and testers can test locally hosted web applications or websites on cloud-based real machines with LambdaTest Tunnel Docker Extension, a secure and easy-to-use encrypted tunneling feature. It establishes a secure connection between the user’s local and cloud machines.

LambdaTest Tunnel Docker Extension connects securely to LambdaTest cloud servers, even behind corporate firewalls. It allows you to test locally hosted websites or web applications across various browsers, devices, and operating systems. LambdaTest Tunnel Docker Extension can test web files written in HTML, CSS, PHP, Python, or similar languages.
