About SnapMock
SnapMock is a free, open-use screenshot mockup generator that runs entirely in your browser. Upload a screenshot, pick a device frame and background, and download a polished mockup — all without creating an account, paying anything, or uploading your images to a server.
Why We Built SnapMock
We're indie developers ourselves. Every time we launched a side project, we hit the same wall: making it look good. Creating professional mockups for landing pages, social media posts, and App Store listings meant either spending hours in Photoshop or paying for a tool with yet another monthly subscription.
Most "free" mockup generators turned out to be free-ish — they'd slap a watermark on your export, limit you to 3 downloads, or gate the best features behind a paywall. We wanted something genuinely free with no strings attached.
So we built SnapMock: the mockup tool we wished existed.
What Makes SnapMock Different
🔒 100% Client-Side
Your images never leave your device. Everything is processed in your browser using the HTML Canvas API. No server uploads, no cloud processing, no data collection.
💰 Actually Free
No freemium tricks. No watermarks. No signup walls. No "premium" features. Every feature is available to everyone, forever.
⚡ Fast
Upload → customize → download in under 30 seconds. No loading screens, no account creation, no tutorials to sit through.
🎨 Feature-Rich
Browser, phone, tablet, and laptop frames. 20+ gradient backgrounds. Mesh gradients. Perspective views. App Store screenshot generator. Multi-image layouts. Retina export.
How SnapMock is Sustained
SnapMock is free to use, but it costs money to run (hosting, domain, development time). We sustain the project through:
- Advertising: Non-intrusive display ads on landing and content pages
- Organic traffic: We write genuinely useful content about mockups, design, and app marketing to attract visitors through search
We'll never charge for the core tool, add watermarks, or limit exports. That's a promise.
Who Made This
SnapMock is built and maintained by an indie developer based in the US. It started as a personal tool for creating App Store screenshots and evolved into a full-featured mockup generator after realizing other developers had the same need.
The project is a solo effort — design, development, content, and marketing all done by one person with a passion for building useful tools.
