CryptPad is an open-source, end-to-end encrypted collaborative office suite that synchronizes documents in real time. It includes rich text, spreadsheets, presentations, forms, kanban, code/markdown, and whiteboard apps, with all data encrypted in the browser so even server administrators cannot read user content.

Use cases

• collaboratively edit documents in real time without exposing content to the server
• self-host a private Google Docs alternative
• share encrypted documents via password-protected links
• run a privacy-first collaboration suite for a team or organization
• collect survey responses with encrypted forms
• manage team drives, calendars, and kanban boards privately

When to choose

• you need end-to-end encryption for collaborative documents
• you want a self-hostable, open-source office suite
• privacy compliance or zero-knowledge storage is a requirement
• you need real-time collaboration across many document types

When to avoid

• you need heavy offline desktop office features like advanced spreadsheet macros
• you require deep integration with third-party cloud ecosystems
• you need a native mobile or desktop application rather than a web app
