I’m Dawid Młynarz, co-founder of CSS Peeper. I’ve been a designer for 13+ years, and like many of you, I constantly found myself digging through dev tools just to grab styles, colors, assets, or spacing. It was slow, frustrating, and honestly pulled me away from the creative part of design. On top of that, I had to install multiple different extensions just to cover the basics.

That pain led me to create CSS Peeper back in 2016, a tool built for designers, but also for developers. Instead of inspecting messy code, you can instantly see and extract the styles you need, in a clean and intuitive way.

Since then, CSS Peeper has grown to a community of over 500,000 users worldwide. Designers tell us they love it because it saves them hours of work, whether they’re grabbing colors from a website, exporting assets, or quickly checking spacing and typography.

What makes CSS Peeper different? It’s focused entirely on designers’ workflows. Instead of overwhelming you with developer-focused tools, it gives you exactly what you need in seconds, without the clutter.

Recently, we’ve taken things a step further with some exciting advanced features to boost productivity even more. Think of it as your one-stop toolkit for peeking under the hood of any site. Fast, simple, and built with your creative process in mind.

I started CSS Peeper to solve my own problem, but seeing how much time it’s saved other designers has been the most rewarding part of this journey. I’m here because I want to keep making your work easier, so you can focus on what really matters: creating great design.

What’s the origin of the idea for your product?

Back in 2016, I was struggling with something that many of you might relate to... digging through dev tools just to grab relevant web styles. It was a painful, repetitive process, and on top of that I needed multiple different extensions just to get simple things done. So I decided to fix it. That’s how CSS Peeper was born, a tool made by a designer, for designers.
