width4blocs is a simple and free breakpoint bric. When you change the size of the window, the respective breakpoint is displayed in the upper left corner of the window.
Each breakpoint is symbolized by an icon and a short text. Furthermore, the size of the Bric can be changed (specified in pixels) and there is a preview mode.
