We created a free open-source mockup generator that exports pixel-perfect social previews. Thoughts?
After spending countless hours taking screenshots and manually editing them in Figma, we built a zero-login browser tool that creates high-res mockups for Reddit, Twitter, Instagram, and more. Feedback appreciated!

Platform Comparison: When to Use Which Mockup
X / Twitter Mockups
Best for short-form announcements, product drops, thought-leadership quotes, breaking news, customer interactions, and fast-paced viral commentary.
A social media post mockup is a realistic-looking simulation of how a post would appear on a platform like X/Twitter or Instagram. It mimics the actual UI — including profile information, post content, metrics, and action buttons — without requiring a real account or published post. Designers, marketers, and content creators use mockups to preview, present, or demonstrate social media content before publishing it.
Yes, completely free. There is no account required, no watermark on exports by default, and no usage limits. The entire tool runs in your browser — nothing is uploaded to any server.
No. All processing happens entirely in your browser using client-side JavaScript. Your text, images, and generated mockup never leave your device. No data is sent to any server.
Mockups are exported as PNG files, which support transparency and provide lossless quality. The exported image is generated at 2× or 3× screen resolution for sharp display on high-DPI screens.
The generated mockup images are yours to use as you see fit. They are visual representations you've created using the tool. Platform UI elements are depicted in a descriptive, illustrative way consistent with how tools like this operate.
