dosya.dev vs Proton Drive
Proton Drive encrypts every file end to end by default. dosya.dev keeps ordinary files encrypted at rest, so previews, search and public links work, and adds end-to-end encryption in an optional Vault. Here is how that trade plays out, line by line.

At comparable sizes dosya.dev costs less: 500 GB is $2.49/mo against $12.99 for Proton Unlimited, and 2 TB is $6.99/mo against $19.99 for Proton Duo. Proton's plans include Mail, VPN and Pass, which matters if you would pay for those anyway.
Where dosya.dev pulls ahead
More storage for the money
Proton's cheapest Drive plan is 200 GB for $4.99 a month, and the next step up is a 500 GB bundle at $12.99. dosya.dev sells storage on its own, from 100 GB at $1.49/mo to 20 TB, and 500 GB is $2.49/mo.
Protocols your tools already speak
dosya.dev ordinary storage works over an S3-compatible API, WebDAV, a REST API, a CLI and rclone, so backup tools, NAS boxes and scripts connect without a custom client. Proton Drive has no S3 or WebDAV, and its rclone backend is an unofficial beta.
Upload-only file requests
Send a client a link and their files land in one folder, without them seeing anything else or signing up. Proton Drive has no upload-only link today.
You choose where files live
Each dosya.dev workspace picks its location from 46 regions on 6 continents, including 9 inside the EU, on every plan. Proton stores Drive data in Switzerland, Germany or Norway, without a choice.
Where Proton Drive is a better fit
Encryption by default. Every file in Proton Drive is end-to-end encrypted, names included, its apps are open source, and Securitum has audited them. dosya.dev encrypts end to end only inside Vault, and Vault has not yet completed an independent audit. If the rule is that your provider must never be able to read any file, Proton Drive meets it out of the box. Proton's bundles are also good value if you already use its Mail, VPN or Pass.
Read how dosya.dev Vault works, including its threat model and limits, before you move sensitive files.
Moving from Proton Drive
Download from Proton
Use Proton's web or desktop app to download the folders you want to move. Proton decrypts them on your device.
Drag into dosya.dev
Drop the folders into the dosya.dev desktop app on Windows, macOS or Linux, or upload them in the browser.
Seal what is sensitive
Upload private files into a Vault Space instead, so they are encrypted on your device before they leave it.
dosya.dev vs Proton Drive, answered
Is dosya.dev a good Proton Drive alternative?
It depends on what you need encrypted. Proton Drive encrypts every file end to end by default, and its apps are open source and audited; if that is the requirement, Proton is the stronger fit. dosya.dev suits you if you want end-to-end encryption for the files that need it (in Vault) and ordinary storage with previews, search, public links, S3, WebDAV and a Linux app for the rest, at $2.49/mo for 500 GB.
Is dosya.dev end-to-end encrypted like Proton Drive?
Only inside Vault. Ordinary dosya.dev storage is encrypted in transit and at rest with keys our service manages, which is what lets us generate previews, run search and serve public share links. Vault is a separate area where your device encrypts file contents, names and folders before upload, with keys only you and the people you add hold. Vault is included on every plan, Free too, but it is opt-in, and it has not yet completed an independent cryptographic audit.
How do dosya.dev and Proton Drive prices compare?
Proton Drive Plus is $4.99/mo for 200 GB ($3.99/mo billed yearly), and 500 GB comes with Proton Unlimited at $12.99/mo alongside Mail, VPN and Pass. dosya.dev is $1.49/mo for 100 GB, $2.49/mo for 500 GB and $6.99/mo for 2 TB. If you already use Proton Mail and VPN, Proton's bundle can be worth it; for storage alone, dosya.dev costs less per gigabyte.
Can I move my files from Proton Drive to dosya.dev?
Yes, through your own computer. Proton's sign-in needs an interactive two-factor step, so it is not one of the services our servers import from. Download your files from Proton's web or desktop app, then drag them into the dosya.dev desktop app. Put anything sensitive straight into a Vault Space, so it is encrypted on your device again before upload.
Does dosya.dev work on Linux?
Yes. dosya.dev has a Linux desktop app (AppImage and .deb), a CLI, WebDAV mounting and rclone support. Proton Drive does not have a Linux desktop app yet; its autumn 2026 roadmap describes a beta in progress.
Can I collect files from clients?
On dosya.dev, yes: a file request gives anyone an upload link into one folder, without showing them the rest of your files or asking them to sign up. Proton Drive has no upload-only link; the closest option is an editor link to a folder, which also lets the visitor see and download what is already there.
