tabVertikal is a Chrome add-on developed by TabRail that provides lightweight vertical tabs in a side panel. With support for tabGroups, this add-on offers a convenient way to organize and manage your tabs.

One of the key features of tabVertikal is the ability to set the window's title and edit tab titles, allowing for easy identification and customization. The add-on also includes a fuzzy search feature, making it quick and efficient to find specific tabs.

In addition, tabVertikal leverages the native Chrome tabGroups support, enhancing the functionality and usability of this feature. The add-on offers a dark mode and a variety of themes to choose from, allowing users to personalize their browsing experience.

tabVertikal is built with pure and clean code, ensuring fast performance and minimal memory consumption. It consumes 400% less memory than the new tab, making it a lightweight and efficient option for tab management.

It's important to note that tabVertikal is a free add-on and does not use any third-party libraries. It prioritizes user privacy by not tracking any user data.

Please keep in mind that tabVertikal is still in beta, so minor bugs may be present. If you encounter any issues or have suggestions for new features, you can contact the developer at
