CryptPad is an end-to-end encrypted, open-source collaborative office suite built by XWiki. It renders a full range of document types — rich-text pads, spreadsheets, code, markdown, kanban boards, whiteboards and forms — while keeping all data encrypted so the server operator (even a third party) cannot read it. It is a privacy-first alternative to Google Docs and Google Workspace.

Key Features

• End-to-end encryption — all your documents are encrypted before they leave your browser; zero-trust by design.
• Multiple document types — rich text, sheets, code, markdown, slides, kanban, whiteboard, and forms with conditional logic.
• Work anonymously — share and collaborate via a link with no email or account required for guests.
• Self-hostable — run your own instance for full control over data and governance.
• CryptDrive — organise documents, folders and templates in a secure, private file space.
• Real-time synchronisation — changes merge live across everyone working in the same document.
• Open-source and free software — published under the AGPL by a non-profit-minded team that answers user feedback.

Why Use CryptPad?

CryptPad gives you the convenience of an always-online collaboration suite without the surveillance. Because it is end-to-end encrypted and can be self-hosted, it suits journalists, activists, clinicians, educators and companies that must protect confidential documents, while remaining easy enough for everyday team use.

Use Cases

• Collaborative writing and note-taking where confidentiality is critical (legal, medical, journalism).
• Anonymous or low-trust collaboration across organisations that need a shared working space.
• Teaching and training with students who should not need accounts.
• Self-hosted productivity stack replacing Google Workspace or Microsoft 365.

Platform

Web browser (all modern browsers). Self-host on Linux (Node.js).
