BSInfo is a free Chrome add-on developed by Propra. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This add-on displays a box that provides information about the currently used bootstrap version and the current grid breakpoint.

With BSInfo, users can easily access important details about their bootstrap version and grid size. The info box conveniently showcases the bootstrap version being used and the current viewport/grid size. This can be particularly useful for web developers and designers who work with bootstrap frameworks.

Overall, BSInfo is a handy tool for those who want quick access to bootstrap information while working on web development projects. Its simple and straightforward interface makes it easy to use and understand.

Please note that as a reviewer, I am unable to provide personal contact information or suggest contacting the developer for feedback or suggestions.
