What made me definitively switch to Zen
Since Arc went in maintenance mode, I tried MANY browsers and as many of you already know, Zen is the closest to Arc there is. But still, I never achieved to properly set it up to feel like home as Arc does so I came back to Arc every time I tried.
With manifest v3 I really wanted to quit using chromium based browsers and with the help of Claude Code (I know) I managed to build a little tool that properly migrate my Arc setup into Zen.
I'm really happy with the result and am now confident on not switching back to Arc for the first time. I've got Zen setup on my Mac, my Windows, and Firefox on Android all synced up with Firefox account.
Since I'm so happy, I tried to cleanup my vibecoded tool to share it with anyone interested.
This is again a vibecoded tool, I reviewed it (I'm a Software Engineer) but it's still a vibecoded app. I understand that you may have some concerns about it since the process implies you to execute a script into your browser console so I made sure it work in total offline mode, and I encourage you to review it yourself or make it review by someone who can before you use it.
You can find the repo here : https://github.com/jb-machemie/arc2zen and just download the files to start it in full local mode.
Or you can use the Github Pages here : https://jb-machemie.github.io/arc2zen/ for a more convenient way.
For a more complete end-result experience, you can install https://github.com/CosmoCreeper/Sine and the https://github.com/YashjitPal/Arc-2.0 mod to even less notice that you just have quit Arc.
I hope this will help at least one more person than me :)
