ONLYOFFICE vs Proton Docs

ONLYOFFICE

• Organizations that want to host their own office suite
• Teams on Nextcloud, Box, Moodle or Odoo that need document editing there
• Sharing files with clients in separate rooms with their own permissions
• People who want free desktop editors that work offline

Proton Docs

• People who want documents the provider itself cannot read
• Lawyers, doctors and advisers drafting confidential client documents
• Existing Proton Drive users who want a document editor in the same account

ONLYOFFICE

• The free DocSpace Startup plan stops at 3 admins, 12 rooms and 2 GB, and lacks SAML SSO, LDAP, branding, a custom domain and the audit trail.
• DocSpace Business costs $20 per admin a month; the pricing page shows it as reduced from $30 and gives no end date for that price.
• Docs Enterprise is licensed by simultaneous connections, from $1,500 for a 1-year, 50-connection, on-premises license with Basic support.
• A 1-year Docs Enterprise license stops working when it ends; a lifetime license keeps running but loses free updates after its support period.

Proton Docs

• There is no standalone Docs plan: it is part of Proton Drive, and the paid plans differ in storage and bundled Proton services.
• A document can be no larger than 25 MB.
• In the Windows and macOS Drive apps a document is only a placeholder file that opens in the browser at docs.proton.me.
• The free plan's 5 GB of storage is shared with the files and photos kept in Proton Drive.

ONLYOFFICE

Document, sheet and slide editors

Online editors for text documents, spreadsheets and presentations, which the vendor describes as highly compatible with Microsoft Office and OpenDocument formats.

PDF editor and fillable forms

Build fillable PDF forms and have them filled in online, read and edit PDFs, and convert documents to Markdown, HTML or e-books.

Real-time co-editing

Co-edit in character-level or paragraph-level mode, track changes, compare documents, leave comments and mentions, and chat or call from inside the editor.

DocSpace rooms

DocSpace sorts files into rooms with their own access rights: collaboration, public, form-filling and custom rooms, and virtual data rooms.

AI assistants and agents

AI tools generate documents, sheets, slides and forms, rewrite and translate text, and extract text from scanned PDFs. Any AI model can be connected, including a fully local one.

Connectors and self-hosting

More than 40 ready-made connectors add the editors to platforms such as Nextcloud, Box, Moodle, Odoo and WordPress, and the server can run on your own infrastructure.

Proton Docs

End-to-end encryption

Documents are encrypted on your device before they are uploaded, and only you hold the keys, so nobody else can read them. Proton says that includes Proton itself.

Real-time collaboration

See who else is viewing or editing a document and follow their cursors live. Every update stays end-to-end encrypted.

Suggestions and comments

Collaborators can propose edits as highlighted suggestions to accept or reject, and discuss a passage in threaded comments attached to the text.

Sharing controls

Invite people by email or with a sharing link, including people without a Proton Account, choose whether they can view or edit, and revoke access at any time.

Import and export

Opens .docx, .txt, .md and .html files stored in Proton Drive for editing, and downloads documents as .docx, .html, .txt, .md or .pdf.

Rich text editing

The toolbar covers text styles, fonts, colors and highlights, code blocks, numbered, bulleted and check lists, quotes, dividers, images and tables.
