Simple Url Switcher is a free Chrome add-on developed by lp177. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This program allows users to switch URLs seamlessly between devices.

With Simple Url Switcher, users can fluidly switch between devices like computers and smartphones while maintaining their current progression on platforms like YouTube and SoundCloud. By simply clicking on the extension icon, users can save the current page to their selected server, along with a timestamp if enabled for the website.

To access the saved page on other devices where the extension is not installed, users can either visit the swap.html file on their server or right-click on the extension button and select "open here." Currently, media time is only preserved on specific websites such as SoundCloud, Twitch, YouTube, and Radio France.

Users can create their own server by following a basic example provided in the extension settings. The server file, swap.php, needs to be created with a random token key (replacing MY_TOKEN_KEY_HERE) for authentication purposes.

Overall, Simple Url Switcher offers a convenient way to switch URLs between devices and preserve media time on supported websites.
