Thought this browser had potential. But now seems to be abandonware at this point. Tried the Pro subscription, which didn't work, but got no response when I contacted them through several different channels, and received no refund. All social media has been silent for months.

Comments and Reviews
Before my review, I want to note the other 2 commenters, their reviews sound a bit odd if not fake. They like the browser's "privacy" for which proprietary browsers have a worse reputation than open source like firefox. And what VPN are they talking about, I couldn't find it...?
SigmaOS design is great. It beats Arc Browser (the closes comparison) on everything. SigmaOS is 45MB and leverages Safari's WebKit under the hood but still supports chrome extensions. Works out of the box and settings (like Adblocker) are easy to change.
I recommend SigmaOS over Arc Browser for Mac users.
Downsides:
Sigma's own Adblocking doesn't look good, adblock-tester.com gives 70/100 when uBlock Origin Extension gives me 96+/100 on all other browsers.
I ran it through browserbench.org, and the other browsers left it in the dust.
It doesn't look like it is particularly fast or private. Good design is all it has for itself.

Switched to it from better known browsers as I was looking for high data protection. What was my surprise to find SigmaOS. Immediately noted its high speed of both the browser and the Internet with VPN connected. No more worries: my data is in safe hands.
I never thought that using a VPN could be so convenient and safe! Thanks to this browser, I can work and surf the web without worrying about my privacy.
The browser makes other competitors such as chrome feel outdated. Helps you be very much more productive, is more advanced (for example, you can input commands into the search bar called “lazy bar” into the browser). Very lightweight as well.
