Achieve Pixel-Perfect Implementation with Design Mirror for Figma
I've lost count of how many times I've done this dance: write some CSS, refresh the browser, take a screenshot, paste it into Figma. I needed a better way.
I've lost count of how many times I've done this dance: write some CSS, refresh the browser, take a screenshot, paste it into Figma, overlay it on the design, spot the differences, go back to VS Code, adjust, repeat.
It's tedious. It's slow. And despite the effort, I'd still miss things—a padding that's 12px instead of 16px, a font weight that's slightly off.
I needed a better way.
The Workflow Problem
When you're implementing a design, you're constantly context-switching. Figma in one window, your code editor in another, browser somewhere else. You're trying to hold the design in your head while you code, then visually comparing afterwards.
The mental overhead adds up. And the pixel-level details? They slip through.
What If the Design Could Float on Top?
The idea was simple: what if I could see the Figma design directly on top of my implementation? A transparent overlay that I could position over my browser, letting me see exactly where things don't match.
That's Design Mirror for Figma.
How It Works
- Connect to Figma via secure OAuth—your actual Figma files, not screenshots
- Select any frame from your projects
- Position the overlay over your browser window
- Adjust opacity and scale to see both the design and your implementation
- Code with precision — differences become immediately obvious
No more switching between windows. No more "does this look right?" Just direct visual comparison.
Features Born from Real Development
Every feature came from my own front-end workflow:
- Multi-display support because I code on one screen and preview in the browser on another
- Keyboard shortcuts because constantly reaching for the mouse breaks flow
- Precision controls because sometimes you need to nudge the overlay 1px at a time
- Auto-sizing — the overlay matches the exact dimensions of your Figma frame, so your browser preview is always the right size
Privacy Respected
The app only accesses Figma files you explicitly select. No tracking, no analytics. Settings are stored locally and in your iCloud. I built this for my own design work—I'm not interested in knowing anything about yours.
The Result
I ship more polished websites now. Those subtle details that used to slip through—the margins, the spacing, the alignment—they're caught before I commit. The tool paid for itself the first time I caught a misaligned element before a client review.
Requirements
- macOS 15.5 or later
- Figma account
- Internet connection for Figma integration
- Honestly, just an export of the design works too
