usually I design in Sketch (switched from PS a year ago), but this is designed for Sparkle in Sparkle - www.sparkle.cx . It’s a good tool for designing your own websites. The biggest advantage is that it’s native mac app => faster than tools like this in browser (froont, webydo, macaw etc.), but Sketch and PS are still better.
I’ve designed 3 different sites on different topic and then hit export. Check the results.
Psalm 23 (my favourite)
Have a nice day!
