Thank you all for help.
Everyone is asking why someone would want an app, just configure openvpn or wireguard!
One of the two major reasons to use a VPN service is to get around geo-restrictions. Are you going to download and setup a new config every time you want to connect through a server at a different country? An app makes this trivial, just select the country and it handles everything for you.
I use NordVPN because I’ve gotten ridiculous deals from them, their Linux app is in the AUR and their browser extensions work well. I don’t recommend their service over others, I only use them because of the stupidly cheap deals I’ve been able to get and I only use them for evading geo-restrictions.
Try Bless VPN, this VPN supports Linux platform, I use it on XUbuntu, works fine for me.
I use PIA to connect to different gateways in the whole world, depending on my needs.
FWIW, I use PIA. I has an official app.
for real. you’d think an arch user would be looking for how to do this in the terminal. I just run:
sudo wg-quick up wg0
I use surfshark. Thinking of proton vpn.
I will not pay for the unknown shady vpn service just for official Arch support. Just wanted to know 
wg-quick is pretty fool proof!
The only time I ever paid for a VPN was when I bought a lifetime license for Windscribe not long after they first released.
I got REALLY lucky. I highly recommend Windscribe
I use windscribe too. I made my own plan and pay $5 a month for it.
For example from PIA you can download configs for all their servers, I have a few of them imported. This is a one time setup thing. So you can just use the tray application to swap which one to use. Not much different than using an official client.
No Linux distribution has official support for ZFS (not even Oracle Linux and they own ZFS) due to licensing issues, the CDDL license ZFS has conflicts with the GPL license Linux has. I would know this because I’ve installed ZFS on both Arch and Debian, they both specify that it’s not officially supported and if it breaks it’s not their fault.
I’ll take the risk of looking stupid if it saves someone else the time / trouble. If you’re looking for the wg-quick package and can’t find it (like I couldn’t), it’s because wg-quick is provided by the wireguard-tools package. 
I use ProtonVPN myself. The native app is improving and much better than what it was before, but there’s still some minor gotchas like port forwarding not being automatically setup like the Windows app does it. It will at least automatically pick out port forwarding enabled servers, but you have to manually run a bash one-liner to periodically request and refresh the port number.
Manually importing their wireguard certs are always an option and I did that for a very long time before v4 of their app.
You can keep Surfshark and set networkManager. Of course changing server with the app is convenient but if you normally connect to the same server…
Like others are saying you don’t need the branded app to use it. Just set it up manually. You could also just download the surfshark extension in Firefox and use that way anyway you’re surfing the web if you really need to.
Have you ever used surfshark or nordvpn?
Could you compare them to Proton? I have bought surfshark subscription about 3 years ago (huge discount) but now I would like to move to something better (probably not need anything better but…)
The AUR is a strength. What does it matter if packages are “officially supported” by the Arch maintainers if they work just fine?
sometimes the user is a bad fit for the operating system. AUR not being supported by Arch Linux does not mean packages in AUR are not supported.
Commenting here suggesting someone change their operating system because they’re looking for help finding an application is the dumbest suggestion in this thread.
Can’t speak to SurfShark but I used Nord at first then it came out that there were some I think Google trackers or data being sold or something like that so they lost credibility for me.
As for a technical comparison Proton has more servers in more countries and has their Super Secure 3 servers that they sourced tech from only US and EU manufacturers, hand-built it and hand-delivered it to their secure locations and you double VPN through them so there’s that if you need utmost security and anonymity. I believe they still have Tor over VPN and Double VPN features as well.
For speed they’re about the same but I did get faster speeds through Proton when I tested them back-to-back a few years ago like 100 or 200 mbps faster.
So to me proton is a no-brainer in terms of which VPN you want for security and it comes with 100gb (or 500 if you pay like $4 more) encrypted cloud storage and email bonuses and something else I forget so it’s more expensive but you get more with it, too and the company is much more trustworthy than its competitors.
And idk about the others but Arch Wiki has a guide on how to setup Proton VPN with Arch but that guide isn’t a client like you’re looking for.
