TL;DR: If you’re a Linux user, you probably don’t want to pay for Proton VPN (yet).

If you search this subreddit, you’ll find a lot of people saying that. However, I thought I’d go into a little more detail. I hope it helps some folks!

First off, let me say: I love Proton, I love their mission, and I’m a (mostly) happy user of Proton Mail, Calendar, and even Drive. I also had a very good experience with Proton VPN on Android. In short, I’m not a Proton-hater (if such a thing is even possible).

I’m writing this because I wish I had read something like it before plunking down my cash for Proton Unlimited. (I upgraded from “Mail Plus” solely for the addition of the VPN. And because I was happy for an excuse to give Proton more of my money, frankly.) First, a message to the Proton team

I’ll just quote my own message from a relevant Github issue:

Sounds like y'all are pretty understaffed and I'm sure it's not your decision directly, but I will say: leaving a clearly half-finished client as the only option for (paying) customers while a new client is in the works -- and scrolling up, this thread has been open for over a year now -- well, I think y'all will start to burn through good will pretty quickly.

My honest suggestion would be: take a pause from the new client development for a month. Squash some bugs. Plug some memory leaks. Make the current client stable and unbroken. (Not talking new features even, just... not broken.) Put it in a decent spot, then leave it to focus on the new client. (And even then, if bugs come up in the old client, I think you have a responsibility to fix them.)

Also, seeing something happen on the current client will make your (paying!) customers feel less abandoned. (Take me for example: as I said, I love the Proton mission, but even I feel like this is a bit of a bait-and-switch.)

And as an addendum: if you’re not going to implement actual fixes, please put an asterisk on the Proton VPN marketing copy, be clear about your (lack of) Linux support. Call it a “beta” client, explicitly say which features are not supported. Something, anything. State of the Linux VPN client: A summary

It’s Pretty Bad. GUI client

No wireguard

No split-tunneling

No port-forwarding

No profiles

Broken search functionality

Slow, unresponsive UI

Lacking basic usability features (e.g. "connect to fastest server that supports P2P", "connect to last server", etc.)

Changing VPN connection state breaks many other applications (including Dropbox, Steam, etc.), requiring a restart

Horrible memory leaks

I’ve put the memory leaks in bold because it’s essentially a blocker. If you leave the GUI client open, it will slowly devour your memory. For me, this usually resulted in a client crash.

Summary: Don’t use the GUI client. Like, period. Command-line client

No wireguard

No split-tunneling

No port-forwarding

No profiles

Changing VPN connection state breaks many other applications (including Dropbox, Steam, etc.), requiring a restart

Takes minutes to establish initial connection

The CLI client is a big improvement over the GUI client. It (mostly) works! You can (e.g.) connect to a P2P- or Tor-enabled server easily, or the fastest server in a given country. Also, it does not hemorrhage memory.

However, its initial connection takes minutes. I can’t imagine why. I didn’t have this issue with the GUI client. (It’s slow, but not that slow.) Note that if you have the kill switch enabled (which you should!), you have no network at all during this time. (By the way: after that initial connection, e.g. if you disconnect and reconnect, it’s not nearly as bad.)

Also note that after you’re finally connected, many apps that will have started during that time will silently have lost their network connection. (Possibly a kill switch bug?) Dropbox and Steam were two obvious and consistent examples of this for me. This also happens when resuming from suspend, or any time the VPN connection status changes for any reason, manual or otherwise. This is also consistent for me – happens every time. I do not experience this with any other Linux VPN client.

Summary: The command-line client is way better than the GUI client, but still worse than many other (non-Proton) Linux VPN clients. Using the provided wireguard profiles

This is a decent possible alternative, but it’s a very manual process.

You login to your VPN account on the web, use the provided interface to download a wireguard configuration for a single server, and then you can use Network Manager or whatever you want to connect to that server.

There’s no bulk-download option, no way to dynamically connect to servers in different regions based on capabilities or load. This is a downgrade from just about any other VPN client out there. The only upsides are: you avoid having to use Proton’s own client and you get support for wireguard (and port-forwarding!).

I considered building some tooling to automate the process of finding the fastest server with a given set of capabilities, pulling down the wg config, and connecting to it. Then I realized: what am I even paying for, at that point? Easier just to use a different provider. Final note

I’m not writing this (just) to complain – more for visibility. Both for the Proton team as well as potential users. If I had read something like this before paying for the service, I simply would have continued using my existing VPN and kept my eye out for the arrival of the “new” Proton Linux client at some point in the future.

But finding all this out after-the-fact – after reading various glowing reviews, marketing copy, and after paying for a subscription – is enough to leave a sour taste in any user’s mouth.

    +1 on this. The client is usable but terrible. I also use NextDNS and each time that I connect I have to restart it because ProtonVPN make some type of conflict. Please fix it. You are a so good company in which we trust for privacy and many of us use linux as os.
