Dimmy.club is a fully free mockup generator for common devices (MacBooks, iMacs, laptops, and phones), with deliberately minimal customization (upload your design, pick a background color, done).
The minimal feature set is itself the value: no signup, no paywall, no decision fatigue over dozens of options when you just need a clean device shot fast.
Good for the simplest, fastest possible mockup need: less suited if you want scene styling, 3D angles, or branding customization.
Customization is genuinely limited compared to paid tools in this category: if you need more control, expect to outgrow it quickly.
Fully free with no paid tier or account required. The tool's minimal feature set (upload, pick a background, done) is the entire product.
