What is the difference between CryptPad and Proton Drive?
CryptPad is an end-to-end encrypted office suite for real-time collaboration, while Proton Drive is end-to-end encrypted cloud storage that includes Proton Docs and Proton Sheets for editing.
CryptPad runs in the browser and covers rich-text documents, spreadsheets, presentations, kanban boards, forms, whiteboards, diagrams, and code files, with CryptDrive organizing them into folders. Proton Drive centers on storing and syncing files: desktop sync for Windows and macOS, automatic mobile photo backup, collaborative albums, and password-protected sharing links with expiration dates, plus encrypted Proton Docs and Proton Sheets. The two overlap on encrypted collaborative documents and spreadsheets, but CryptPad covers more document types and Proton Drive covers more devices.
CryptPad vs Proton Drive pricing: which costs less?
CryptPad costs less if you self-host, since the AGPL-3.0 software has no license fee; on hosted plans, Proton Drive gives more free storage (5 GB vs 1GB) and 200 GB for $4.99/month, while CryptPad.fr paid plans start at roughly €5/month.
CryptPad.fr paid plans range from roughly €5 to €100/month depending on storage tier and include priority support. CryptPad Enterprise, a managed instance with SSO and guaranteed response times, lists at roughly €3,000/year for the smallest tier, around €1,500/year for nonprofits and education, and about €25,000/year for 1,000 users and 1TB. Proton Drive Plus is $4.99/month for 200 GB, Proton Unlimited is $12.99/month for 500 GB plus Mail, VPN, Calendar, and Pass, and Proton Duo is $16.99/month for 2 TB shared by 2 users, each with a 30-day money-back guarantee.
Is CryptPad more private than Proton Drive?
CryptPad and Proton Drive both encrypt content on the device so neither provider can read it, but CryptPad can be self-hosted on your own servers while Proton Drive keeps encrypted files on Proton's servers in Switzerland.
CryptPad encrypts every document type client-side, so even an instance's administrators cannot read stored content as long as the code is unmodified, and CryptPad can run on your own infrastructure or be used anonymously without an account. Proton Drive encrypts files before upload, publishes its GPL-3.0 client code on GitHub, has had the clients independently audited, and operates under Swiss privacy law. Both models carry trade-offs: CryptPad's encryption rules out server-side search and AI features, and Proton cannot recover a lost password for encrypted files without a saved recovery kit.
Which is easier to use, CryptPad or Proton Drive?
Proton Drive is easier to use, with a low learning curve and native apps for Windows, macOS, iOS, and Android, against CryptPad's moderate learning curve and browser-only access.
Proton Drive works like familiar cloud storage: install the Windows or macOS sync client or the iOS or Android app, and phone photos and videos back up automatically. CryptPad runs entirely in the browser, which avoids installs, but its real-time collaboration and UI responsiveness feel less polished than Google Workspace or Microsoft 365. Teams that self-host CryptPad also take on running and maintaining their own server infrastructure to get the zero-trust guarantee.
Strengths and weaknesses
