Proton has confirmed that it is actively building a native Proton Drive client for Linux, handling one of the most requested missing pieces in its encrypted cloud storage service.
For those unfamiliar, Proton Drive is Proton’s privacy-focused cloud storage service, similar in basic purpose to Google Drive, Dropbox, or OneDrive, but built around end-to-end encryption. It lets users store, sync, access, and share files online while keeping file contents protected so that Proton itself cannot view them.
The service is available in both free and paid versions. Proton Drive’s free plan offers up to 5 GB of encrypted cloud storage, while paid plans increase the available storage. Proton currently lists Drive Plus with 200 GB, Proton Unlimited with 500 GB, and Proton Duo with 2 TB, alongside business plans for teams.
The Linux confirmation appeared as part of Proton’s June 2026 update on its Drive SDK, which now serves as the shared technical foundation behind Drive across platforms. According to Proton, the Linux client is being built from the ground up to take advantage of that SDK.
“We’re also now actively building one of the community’s most-requested features: the Proton Drive client for Linux, built from the ground up to leverage the SDK.”
Let’s be clear: Proton Drive for Linux has not been released yet, and Proton has not announced a launch date. However, this is the clearest official confirmation so far that a native Linux desktop client is not simply a community request or a long-term possibility, but a real development effort.
Proton Drive is already available through the web, and desktop apps exist for Windows and macOS, while mobile apps cover Android and iOS. Linux users, however, have had to rely on the web interface or unofficial third-party solutions.
The SDK update also brings performance improvements to Proton Drive. Proton says uploads are now up to three times faster, while downloads are up to two times faster. The company also says the cryptographic model has been improved, enabling new files to be end-to-end encrypted up to four times faster.
Beyond desktop sync, Proton says the SDK should make Proton Drive easier to integrate with other Proton services and external tools over time. One example already mentioned by the company is integration with Lumo, Proton’s privacy-focused AI assistant, allowing documents stored in Proton Drive to be used while keeping them protected by end-to-end encryption.
So, for now, Linux users still do not have an official Proton Drive desktop client to install. The good news, however, is that this is about to change.
