Zen Browser vs SigmaOS

Zen Browser is heavily inspired by Arc Browser, with one core difference. It was built for those who want a Chromium alternative, but love the idea of a modern browser with a powerful sidebar, like Arc.

That said, with it being built atop Firefox, if you're moving over to it from Google Chrome or Safari, you're most notably going to notice how many browser extensions you use that don't exist in Firefox more than anything:

Only 2 of 29 extensions ported over

It's also built by a much smaller team, so you really have to just be somebody that absolutely loves Firefox, and wants to use a modern spin on that. That said, if youwant an Arc-like experience without the bugs? Just use Arc instead.

SigmaOS is a more unique productivity browser in the space.

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.
