FAQ
What is the best AppMockUp alternative?
Mockly — the native-Mac version. Same device-framed multi-language screenshots, rendered locally in 3D, no watermark, AI translation via your own key, ASC upload, $12.99 once.
Does Mockly add a watermark like AppMockUp's free tier?
No — clean, watermark-free exports at every required size. AppMockUp's free tier typically applies a watermark or limits.
Is AppMockUp free, and why pay for Mockly?
AppMockUp's free browser tier is great for a quick framed shot. Mockly is $12.99 once and worth it for no watermark, on-device 3D rendering, AI translation with your own key, and direct ASC upload — a repeatable, private, submission-ready workflow.
Does Mockly support the same device sizes as AppMockUp?
Yes — every size App Store Connect requires, including visionOS and Apple Watch, from one project.
Does Mockly render on-device unlike a web tool?
Yes — entirely on your Mac with Metal 3D, nothing uploaded. AppMockUp is browser-based. For pre-release work, on-device is safer.
Does Mockly translate screenshots like AppMockUp?
Yes, with a privacy difference: Mockly calls your own AI translation API key from your Mac, so the text stays between you and your provider.
