Proton Drive SDK update: faster, more reliable Drive apps

General
1

Proton Drive apps now feature up to 60% faster uploads on iOS and 30% faster uploads and 70% faster downloads on web.

The SDKs don’t cover every workflow yet, especially with some features still in development. To fill that gap, we’re working on command-line interface (CLI) tools that provide Drive functionality not yet available in the SDKs. You will be able to:
  • Run commands directly for common tasks
  • Build on top of them without reverse‑engineering Proton Drive

We’re aiming to make these CLI tools available in the next quarter (April – June 2026).

Over the course of 2026, we’ll migrate all existing Proton Drive features to the SDK, and build all new features on top of it. Our priorities are to:

  • Complete the SDK rollout across all Proton Drive clients, so the desktop, mobile, and web apps use the same codebase.

  • Upgrade Drive’s encryption algorithms to use on‑device hardware acceleration, delivering faster operations while reducing CPU usage.

  • Add the still-missing Drive features to the SDK, starting with Photos uploads and downloads, file sharing, devices, and file revisions.

  • Gradually move toward a single, well‑documented integration path that third‑party apps can rely on.

  • Build a Linux client using the SDK, which speeds up development and keeps it consistent with the other Proton Drive clients.

I hope they hurry up and keep improving it.

Baffling there is still no development on Drive for Linux. They promised (what, over a year ago) that this SDK was the path to basically have community develop that app for them. Their promises for Linux development have repeatedly missed deadlines (by years sometimes). They have repeatedly stated their Linux products are in such terrible state because of a shortage of Linux devs. Well, they currently have 55 job postings up…not a single one is for a Linux dev, and only one is for a Drive dev who is not specific to Android, iOS or Windows. No wonder they don’t have Linux devs, they are making literally zero effort to hire them. Let’s just keep in perspective that this is a company that is just pursuing profit through catering to major (purposefully privacy-invasive) platforms.

Looks like its still planned for 2026.

Under the What’s Next section they have

Build a Linux client using the SDK, which speeds up development and keeps it consistent with the other Proton Drive clients.

They have been promising this for a while.

Glad to see PDrive is improving, but still needs a fair bit of work before I use it regularly

Still waiting on this so I can use obsidian on Android via the cloud rather than locally.
