MockupsJar is a free mockup generator focused on app screens: turning a raw app UI into a realistic device presentation for portfolios or store listings.
The app-specific framing (rather than general device/product mockups) makes it a faster, more targeted choice when the thing you're mocking up is specifically an app screen.
Good for developers and app designers who want a quick, free app-screen mockup without a broader general-purpose tool's extra options getting in the way.
As a smaller, narrowly-focused free tool, expect fewer device and style options than the larger platforms in this category.
The first 20 downloads are free at full resolution; after that, free downloads drop to low-res (640x480px) unless you subscribe. A paid plan (€5/month) adds unlimited full-resolution, watermark-free downloads; a separate API plan starts at €45/month for 1,000 tasks.
Easy-to-use mockup generator for websites, mobile apps and more. No Photoshop needed.
