Although SigmaOS is currently available only for macOS, I am listing a few alternatives for Windows below. Some of them have an option for Windows now while others are still building it. SigmaOS helps you understand what you can expect.
A. The Problem and The Pitch
How do you spend time on your computer? š„ļø
Are you working in apps like Figma or Notion? Or reading articles on Substack? Or responding to mails while you listen to music?

Youāre likely doing something on the web. And your browser is a window to the internet. But browsers havenāt fundamentally evolved since the 90s!

Our browsers are chaotic places. We spend an increasing amount of time surfing the web. We almost unquestionably use Chrome or Safari. Probably because companies that make browsers arenāt fixing the obvious problems that prevent us from being more productive.
š§°Ā User experience is not optimized for using web applications like Notion and Figma
š«Ā Poor multitasking capability. 10+ tabs and your systemās fan goes brrrrrr
ā”Ā Slow default. Speed is not a consideration - be it search, multiple accounts or a keyboard-only interface
What if you had a purpose-made browser for work?
Designed to make you faster and better.
šĀ Thatās SigmaOS š
It is a new type of web browser made for work. Itās as fast as Safari and itās built around workspaces and multitasking.

The first thing youāll notice about SigmaOS is the minimal, unconventional interface. It doesnāt have ātabsā like any mainstream browser but has spaces for you to arrange your webpages and apps. Just like youād organize your files into folders in your system.
Thereās no address bar, cross to close a webpage, or even the ability to bookmark a website.
B. What's special?
SigmaOS is the first step towards the rethink of the modern browser. It pushes you to realize what a better experience can be. It questions what has been āobviousā for decades.
#1 šļøĀ Workspaces: Like Slack, in SigmaOS, your browser activity is separated into workspaces - one workspace per project. So you have separate spaces for work, personal projects, NFT & crypto trading, and entertainment.

#2 ā”Ā Speed: Like Superhuman, SimgaOS is packed with reactive and clever key shortcuts. Snooze pages, search across tabs, share your work and articles instantly. Split screen allows you to multitask like a pro with two active pages at a time. Imagine two pages next to each other: your research and Notion or Google Meet and Figjam.

#3 š¤·Ā Not so special: Lack of extensions like in Chrome. SigmaOS is built on Appleās Webkit framework instead of Googleās Chromium. So you canāt use your favorite password and adblocker extensions in SigmaOS.
The product is in its infancy. So, we can likely expect big things and additional updates as it scales and the community grows šš. It was recently voted Product of the Month on ProductHunt š»

C. What's more?
#1 This space is hot at the moment. On one hand, you have extensions like Workona trying to create a similar experience in Chrome (you can try this in Windows). On the other you have full fledged apps like The Browser Company, Mighty, Vivaldi, and Sidekick reimagining the browsing experience. Iām particularly excited about ā„ļø The Browser Company (Based on Chromium, so all your Chrome extensions work!). Full review coming soon; once theyāre out of private beta.
