We were great fans of the popular mock-up web utility named place.it but soon they turned to their freemium model. They do offer great mock-up images for apps for many platforms but their free images aren’t great to use for products and their paid images are a bit too highly priced for everyone to afford. Mock-ups are good resources for giving an idea of what an App/Product will look like on a particular device and what it will look like from different angles. We have researched and gathered some quality Best Free Mockup Sources on the web for developers so that you don’t have to keep browsing and searching for them.
1] MockDrop: MockDrop is a great tool for a beginner and has many images to surf around till you find the perfect match for your product. It has myriad options for smartphones, laptops, watches, tablets etc. Overall Mockdrop performs great, the only issue we had is that the website sometimes feels laggy.
Content: TV, Desktop, Laptop, Tablet, Smartphone, Watch.
2] SmartMockups: SmartMockups is one of the best mock-up application out there other than MockDrop, Unless you really want more variety of different images, these two should suffice your need for mock-up images. SmartMockups gives great image quality and resolution and their image sizes speak for itself.
Content: Desktop, Laptop, Tablet, Smartphone, Watch.
3] Mockups Jar: Mockups Jar has good content but some good images are locked, it still provides some great variety of content ranging from books, clothes etc.
Content: MacBook, Android, iPhone, Frames, Browser.
4] Magic Mockups: Magic Mockups give that rough & rugged feel to your mockups, the only downside we found in Magic Mockups is that they have very few content to use comparatively to their counterparts.
Content: MacBook, iPhone, iPad, iMac.
5] Mockup World: Mockup World is not just restricted to gadgets, it has awesome collections of PSD’s in books, covers/magazines. Mockup World has that clean & distinctive look some users might prefer to use in their products. It’s worth giving it a look.
Content: Fashion & Apparel, Food & Beverages, iMac, iPad, iPhone, MacBook, Packing, Paper & Books, Signs & Billboards, AppleWatch.
6] Dunnnk: Dunnnk has put some serious efforts to stand out in the game and we personally recommend for watch mock ups. The IOS mockups are great even just to look at, the only downfall is there are few Android mockups available.
Content: iPhone, MacBook, iPad, Android, Apple Watch.
7] Appwrap: Appwrap is a comparatively new tool in the market.
We have not tested it personally We tested it,(It is great) the interface looks great & has many devices listed in their library. Though we could not see any option to add any background image. There is an Android App too which can be found here.
Notable Mentions (In case if you need more):
8] PicApp: Some serious content down there but you won’t get high-resolution images.
Phones: iPhone 7, iPhone 6, iPhone, iPhone, Google, HTC, Samsung etc.
Tablet: iPad Air, iPad Pro, iPad Mini, Google, Samsung, Microsoft.
Laptops: Apple, Asus, Lenovo.
Watch: Apple, Samsung.
9] DropMock: Many Videos available here too.
