LambdaTest Tunnel Docker Extension is designed to streamline local website testing by allowing developers and QA teams to test locally hosted websites and web applications across over 3000 browser and operating system environments without manually launching a tunnel through the CLI. This extension, which integrates seamlessly into existing workflows, provides a secure SSH tunnel for data protection and facilitates advanced configurations such as Proxy Port and Environment settings. By enabling quick setup and access to a vast browser farm, the extension helps developers receive faster feedback on code changes, thus enhancing the overall development process. It also allows for secure testing even behind corporate firewalls, supporting web files written in various programming languages. This tool aims to simplify the testing process, reduce development delays, and improve efficiency by leveraging cloud-based infrastructure.
