SigmaOS gives you fresh ideas inspired by Arc, but charges for features Arc gives away, while Vivaldi feels outdated even though it's highly customizable.

Only use Vivaldi if you absolutely need to rearrange every button in your browser; otherwise, SigmaOS makes more sense.

If you want a browser that feels modern and is trying out new layouts and productivity ideas, SigmaOS stands out with its fresh, opinionated design choices. It's not just another Chrome clone and actually pushes for something different, even if some features are borrowed from Arc.

Vivaldi, on the other hand, is all about deep customization, every button, every color, just how you want it. But that flexibility comes at the cost of a dated, uninspired interface that hasn't kept up with newer browsers. Unless you absolutely need to tweak every single detail because you can't stand standard layouts, Vivaldi just feels stuck in the past.

If you're after a browser that feels current and does things differently, SigmaOS is the better pick. Only go for Vivaldi if extreme customization is your top priority and you don't care about a modern look or workflow.

SigmaOS Editor's Verdict

What is SigmaOS?

SigmaOS is a super interesting primary browser contender in the space. In the myriad of productivity-focused browsers out there.

SigmaOS tried to re-think how a browser layout should be, and build in layers of productivity along the way (not too dissimilar to that of Arc Browser).

The thing is, Sigma has quite minimal funding, and in the browser space, you're competing with companies that have billions of dollars to throw at improving the browser (Google Chrome, Edge, Safari), so when comparing it to those, it's tough to see how they'll manage to compete.

That said, even just comparing SigmaOS to that of Arc, Arc has raised over $100M to take on this incredibly competitive space, whereas SigmaOS is trying to fight having raised likely less than $2M. It's also tough to understand if people are actually willing to pay for a browser, and at $20/mo on the paid tiers for SigmaOS, it just feels like Arc is the more likely winner here.

SigmaOS does make some pretty different opinionated design decisions though, it's worth a shot checking out if you want to try something fresh and new, though not sure we'd bet on it ultimately taking up any meaningful browser marketshare.

Vivaldi Editor's Verdict

What is Vivaldi?

Vivaldi was one of the first browsers to shake up the customization space when it was first released in 2015. Vivaldi came out of nowhere allowing you to customize just about every button along with full color themes, at a time when everyone was using the identical looking version of Chrome, Internet Explorer, and Safari.

This was the unique value proposition of Vivaldi back then, and seems to be the same to this day.

The problem is, when you allow for ultimate customization of every button and color theme, they seem to have locked themselves into an old and uninspiring design. One that looks like it did back in 2015. So at a time when modern solutions are coming out on a monthly bases, and customization and color theming is baked into just about every browser on the market, what once made it unique now leaves it in a questionable situation.
