Polypane has hundreds of tools:
Hi! 👋 I'm Kilian.
I'm the founder, developer, designer and support team at Polypane. Nice to meet you!
I built close to 200 websites in the past decade and I've always been building tools and libraries to improve my workflow. Polypane started as a prototype after getting frustrated that I had to resize my browser all the time. When I started using the prototype I was shocked: I instantly was 60% faster compared to just using Chrome.
And it's not just me. People keep telling me how much more efficient they are. 2 times, 3 times, some even 5 times as efficient!
That's why I'm building Polypane. My mission is to help devs and designers create the best web experiences they can, through a browser that puts them first. Wanna give it a try?
