When is client available on Linux? We are waiting for a very long time now.

I am a Linux Mint user. Having moved from Microsoft Windows I really miss tight operating system integration.

This feature can not come soon enough.

This is absolutely needed.
Having the option to not just sync but also to mount Proton Drive would be an absolute game changer.

I really need this client. For this reason, I am currently considering leaving Proton and choosing another provider.

At my job we want to switch from Macs to pc's with Ubuntu. The only thing really missing is a cloud service to share files and with the possibility to work together on documents. Proton Drive with Proton Docs would be perfect for this, so I hope there will soon be a Linux client for those services.

This one is a BIG need, Proton team!

Proton, people have been begging for this for at least 6 years from what I've seen on the web. And now the Rclone method doesn't work anymore. Please do this already!

I currently have a free Proton account. I would like to upgrade to the Unlimited version, but I won't do so until there is a Linux client for Proton Drive.

I second @Clemens comment. From experience with using both Dropbox and Proton Drive on Windows, I can say that Proton Drive is far from the Gold Standard for speed and reliability between files. Sometimes, edits from either clients are directly in the cloud can take tens of minutes even with <50MB files.

Need this one. Please prioritize this one for a smooth integration into Linux.

Very short, this is a "Must have" functionality

Can we have an answer from Proton to this much wanted sync feature for Linux clients?

Really need this, too. Windows and MacOS but not Linux? Our money is just as good as their users'... :-)

Linux is main operating system in the daily operations of my company.
I believe in Proton's mission but the lack of native integration really hinders our workflow and quite frankly is bordering on being a deal-breaker.
Please do prioritize it.

Bonjour,
Je Bascule sur Linux afin d'abandonner windows aussi pour des raisons de sécurité et si j'ai pris un abonnement Proton, c'est aussi pour des raisons de sécurité. Je suis surpris de découvrir des réticences de votre part pour basculer Proton Drive sous Linux. Nous faudra-t-il rechercher une autre solution à Proton ?

I'm happy with Proton Pass and Mail and ... satisfied with Proton VPN (although it could use some improvement). But I definitely would love to see a Linux version of Proton Drive.

I don't have anything to add to all the comments already posted.
A Linux desktop client will sell Proton subscribtions like crazy, and with the big US tech firms shooing away more and more customers, the potential is huge.
For me, it's super annoying as my desktop PC (graphic design, etc.) is Windows, but my "write on the go" laptop is Linux. For now I have to manually sync stuff via web which is super tedious.

In the coming months and years, we will see a large number of companies and users turning away from Microsoft – every week, I train dozens of people on Linux Zorin and Mint, and this development is unstoppable.

So, we need the Linux Proton Drive version 1 soon – it SELLS Proton :-)

And while we're at it, I have an additional and difficult request for version 2: why not make it as technically sophisticated as Dropbox?

1. Core Difference Between Dropbox and Most Other Drives

Dropbox stands out primarily because of the depth and maturity of its synchronization engine.

Compared to systems such as Nextcloud, Proton Drive, Google Drive, or Microsoft OneDrive, Dropbox is heavily optimized for:
• Efficient block-level delta transfers
• Very low-latency filesystem event handling
• Transaction-safe updates
• Defensive and reliable conflict resolution
• Prioritized syncing of actively modified files

The difference is not primarily about collaboration features, but about synchronization robustness under active desktop workloads.

2. What Would Be Required to Reach That Level

To match Dropbox’s sync reliability, a vendor would need to:
• Implement true block-level delta synchronization
• Integrate deeply with OS-level filesystem change tracking
• Introduce atomic, transaction-like handling of file updates
• Strengthen conflict detection and resolution logic
• Implement intelligent sync prioritization for active working sets

This is mainly a client-engine architecture challenge rather than a server-side feature addition.

⸻

3. Broader Benefits

A more advanced sync architecture would improve:
• Reliability for large and complex project directories
• Stability under rapid, continuous edits
• Data integrity in multi-device workflows
• Reduction of corruption risks
• Overall predictability in professional desktop environments

The primary gain is not new functionality, but higher determinism, resilience, and trust in distributed file synchronization.
