CryptPad

CryptPad is a revolutionary collaboration platform that puts privacy first without sacrificing functionality. Built on zero-knowledge encryption, it ensures that only you and your collaborators can access your documents - not even the server administrators can read your content.

The platform offers a comprehensive suite of collaborative tools including rich text documents, spreadsheets, presentations, code editors, and whiteboards. All editing happens in real-time with multiple users, making it perfect for teams that need to work together seamlessly.

Key advantages include:

• End-to-end encryption for all documents and communications
• No registration required for basic use - share links directly
• Self-hostable open-source solution for complete control
• GDPR compliant with servers located in Europe
• Cross-platform compatibility works in any modern browser

Unlike traditional cloud services, CryptPad operates on a zero-knowledge architecture, meaning your data is encrypted before it leaves your device. This makes it ideal for sensitive business documents, legal work, journalism, or any scenario where confidentiality is paramount.

The platform supports team workspaces, shared folders, and granular permissions, making it suitable for both individual users and organizations seeking a privacy-focused alternative to mainstream collaboration tools.
