Encrypted real-time office suite: documents, spreadsheets, presentations, and more, all client-side encrypted.
Core Features
- End-to-end encryption: data encrypted in browser, server never sees plaintext
- All-in-one tools: Document, Sheet, Presentation, Form, Kanban, Code, Rich Text, Whiteboard
- Real-time collaboration: simultaneous editing with instant sync
- Self-hostable: Docker images and traditional install for full control
- Open source & auditable: AGPLv3 license, community vetted
What It Can't Do
- •End-to-end encryption requires trusting the server admin not to serve malicious code; use well-known instances. 2. Your IP may be logged; use Tor Browser for anonymity. 3. Always use the latest version to benefit from security patches. 4. Shared links grant access to the document; manage sharing carefully.
Use Cases
- Secure team collaboration without trusting cloud providers
- Privacy-conscious users needing encrypted online office tools
- Organizations hosting their own collaboration platform on-premises
Detailed Introduction
CryptPad is a fully open-source collaboration platform that encrypts all data in your browser before it reaches the server. It offers a full set of office-like tools — documents, spreadsheets, presentations, forms, kanban boards, code snippets, rich text, and whiteboards — all with real-time synchronization. Because encryption happens client-side, even if the server is breached, attackers cannot read your content. The software is designed to minimize data exposure: no passwords are sent to the server (keys derived from username+password), and IP logging is a risk you should assume exists. A well-maintained instance includes safeguards against script injection and other attacks. CryptPad is actively developed by XWiki SAS and has a three-month release cycle. It can be self-hosted via Docker or traditional installation, with official Docker images for AMD64 and ARM64. The community translates the interface through Weblate and discusses on Matrix and the CryptPad forum.
