The floor beneath his chair vanished. As he fell into the nightmare, the last thing Elias heard was the chime of a bell and a woman’s voice—sweet and sharp like a razor—asking him if he preferred a life of order or a beautiful, screaming chaos.

The cursor blinked rhythmically, a tiny heartbeat on the edge of a decision. Elias had spent weeks scouring deep-web forums for this specific archived build: .

Suddenly, the temperature in his apartment plummeted. The smell of old wood and cheap rum—the exact scent of the Stray Sheep bar from the game—wafted through his room. His monitor didn't show a game menu; it became a window. On the screen, Vincent was sitting at the bar, but he wasn't looking at his drink. He was looking directly at Elias.

He opened WakeUp.txt . It contained only one line:

He realized then that the "Classic" version wasn't a game at all. It was an invitation to fill a vacant spot in the tower.

Elias spun around. The shadows of his coat rack had lengthened into the shape of a massive, twisted staircase. The walls of his apartment began to crumble, revealing an endless, dark void filled with the bleating of sheep.

"You shouldn't have opened it," the digital Vincent whispered, his voice coming not from the speakers, but from the corner of the room behind Elias.

He looked back at his computer. The .zip file had renamed itself. It now read: .

Privacy & Security 🔒

Your privacy and security are our top priorities

No Data Collection

Web Design Ruler operates entirely on your device. We don't collect, store, or transmit any of your data or browsing history to our servers or third parties.

Clean Code

No ads, no trackers, no bloat. The extension is built with clean, efficient code focused solely on providing helpful design tools.

The extension is built with transparent practices. You can inspect the code yourself since it's installed as an unpacked extension.

Works Offline

All functionality works completely offline. No internet connection is required for the tools to operate after installation.

Why We Built This 💡

As web designers and developers at LXB Studio, we often found ourselves switching between multiple tools to measure elements, identify fonts, and pick colors from websites. This workflow was inefficient and interrupted our creative process.

We built Web Design Ruler to solve these pain points and create a streamlined workflow for ourselves and the design community.

  • Eliminate the need for multiple extensions.
  • Create pixel-perfect designs with accurate measurements.
  • Identify and replicate beautiful typography.
  • Extract exact colors for design consistency.
  • Speed up the web design process.

We've made it free and open because we believe in giving back to the design community that has given us so much.

Frequently Asked Questions ❓

Got questions? We've got answers

Which browsers are supported?

Web Design Ruler works with Google Chrome, Firefox, and Chromium-based browsers like Microsoft Edge, Brave, Opera, and Vivaldi. Install from the Chrome Web Store, Firefox Add-ons, or download the extension files directly.

Is Web Design Ruler free to use?

Yes! Web Design Ruler is completely free to use. We created it to simplify web design workflows and give back to the design community.

Can I use the extension on any website?

Yes, you can use Web Design Ruler on any website. However, it cannot be used on browser pages like the Chrome Web Store, Settings, or New Tab page due to Chrome's security restrictions.

Why is it distributed as an unpacked extension?

We offer both options! You can install from official stores (Chrome Web Store and Firefox Add-ons) or download it as an unpacked extension for those who prefer manual installation or want to inspect the code.

Why can't I delete the extension folder?

Chrome loads unpacked extensions directly from the folder location you specify during installation. If you delete or move this folder, Chrome can no longer find the extension files, and it will stop working. This is different from extensions installed from the Chrome Web Store, which are stored in Chrome's internal storage.

How accurate are the measurements?

The measurement tool provides pixel-perfect accuracy based on the rendered elements in the browser. It measures exactly what you see on screen.

Can it identify all fonts?

The font detector can identify any font that's actively loaded and applied to text on the webpage. It cannot identify fonts in images or custom fonts that use non-standard loading methods.

How do I report bugs or request features?

We welcome your feedback! Please contact us through our contact page to report bugs or suggest new features.
