Zen Browser vs Vivaldi

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.

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.
