the issue with SearX is the search results can be irrelevent or something random.
Haha, oh, right! I just remembered that often times when I searched something completely harmless some weird porn sites would appear in the results which had clearly absolutely nothing to do with the things I’ve been searching for. It’s one of the reasons why I stopped using SearX(NG).
I think you can even port forward with the free plan of ProtonVPN.
You can find many public hosted instances here but some of them use Cloudflare because they fear DDoS attacks. So keep that in mind when choosing your instance. Best is to host your own instance.
Why don’t you use a sync tool to automatically sync your KeePass database when you’re home and just get rid of Bitwarden?
Edit: Or just use Syncthing to always keep your database on all devices in sync. You wouldn’t even need to open ports.
Why the need for a specific mobile app for Mailbox? I use Mailbox in combination with FariEmail app on Android. It even supports PGP. Couldn’t be happier.
It’s just Mullvad and you have to pay 10€. If you buy Mullvad’s VPN service directly from their website you only pay 5€ and you get much more with the client they offer. So if you ask me the better choice is obvious.
