Hi! 👋 I'm Kilian.
I'm the founder, developer, designer and support team at Polypane. Nice to meet you!
I've built close to 200 websites over the past decade, while continuously creating tools and libraries to improve my workflow. Polypane started as a prototype after getting frustrated that I always had to resize my browser. When I started using the prototype, I was shocked. I was instantly 60% faster compared to just using Chrome.
And it's not just me. People keep telling me how much more efficient they are with Polypane. 2 times, 3 times, some even 5 times as efficient!
That's why I continue to develop Polypane. To help devs and designers create the best web experiences they can, through a browser that puts them first. Give it a try!
