Features

Six controls.
Nothing you don't need.

Mockstack is deliberately small. It picks the right phone frame from your screenshot's shape, samples your brand colour, sizes your caption for thumbnail legibility, and stays out of the way. Here's everything it does.

01 · Templates

Six compositions ready to ship.

Hero, Spotlight, Pop, Soft, Midnight, Editorial. Click one and the whole comp loads, background, phone position, type, colors. Replace the copy with yours.

02 · Export all sizes

Six sizes. One ZIP.

iPhone 6.9″, 6.5″, iPad 13″, Android phone, Android phone tall, Android tablet, Mockstack renders each at native resolution and packages a single download. No more re-exporting the same comp six times.

03 · 1-up, 2-up, 3-up fan

One screen, or a fanned set.

Show one feature large, two side-by-side, or three fanned with depth, Mockstack tilts and stacks them so the comp reads instantly. Same background, same type, every comp consistent.

04 · Brand autopick

Backgrounds that match your app.

Upload your screenshot. Mockstack pulls the dominant + accent color and offers four matched backgrounds, solid, gradient, tint, shade, so the comp ties back to your product without you fishing for hex codes.
