My main issue from working with Zeplin is that it can't "explain" the layout, it can only give you dimensions in a specific static scenario. For example, a layout might be based on a grid system that can only be derived from looking holistically at every design artefact (including written words), because any individual layout gives an incomplete piece of the puzzle. Ultimately I found that Zeplin doesn't replace the need to have conversations about most aspects of a design; and whilst it can provide value in some cases, that scope of that value tends to be vastly overstated. If you know that your design system uses a base unit of 8 pixels, you can eyeball most dimensions up to about 8 units, and guess pretty successfully above that.
