arc is developed by The Browser Company. its free, but I don’t believe it’s open source. its basically a UI layer on top of chromium so its performance is about what you would get out of Chrome.
I’m wondering if they’re trustworthy with my data? I use the Brave browser and at least so far they haven’t tried to sell my browsing data. I’ve heard about the selling Brave Search stuff though, so I’m looking for good alternatives.
