LanguageProject Introduction
Summary
CryptPad is a private and open-source collaboration suite. It enables users to work together on documents and files securely, with end-to-end encryption ensuring privacy.
Problem Solved
Existing collaborative office suites often store user data in plaintext on servers, raising privacy concerns. CryptPad solves this by providing a platform where data is encrypted client-side, making it unreadable to the server administrator or third parties.
Core Features
End-to-End Encryption
All data is encrypted in your browser before being sent, meaning the server cannot read the content of your documents.
Real-time Collaborative Suite
Work on documents, spreadsheets, rich text, code, whiteboards, and more simultaneously with others.
Open Source
The entire codebase is open-source, allowing for audits and community contributions.
Self-Hostable
Easily deploy your own instance of CryptPad for full control over your data and infrastructure.
