Cryptpad
App in the BluixApps catalog
What it is
CryptPad is a privacy-first collaboration suite — documents, spreadsheets, presentations, kanban, polls, all with end-to-end encryption. The server has zero access to user content. Originally developed by XWiki SAS in France, with strong privacy guarantees.
For privacy activists, journalists, and orgs handling highly sensitive collaborative documents, CryptPad's E2E encryption is the gold standard.
What it's for
- E2E-encrypted documents — no plaintext on the server
- Collaborative editing — multi-user real-time
- Sensitive content — journalism, legal, healthcare, activism
- Anonymous collaboration — no account required
- Privacy-first apps — pads, sheets, presentations, kanban, polls
Who it's for
- Privacy-bound orgs handling sensitive collaborative content
- Journalists / activists with source-protection requirements
- Legal firms working on confidential matters
- Healthcare under HIPAA collaborative document constraints
- Privacy researchers demonstrating E2EE-capable collaboration
Why teams pick CryptPad over alternatives
- AGPLv3 — fully open
- True E2EE — server has no access to content
- No account required — anonymous use works
- Document variety — text, sheets, slides, kanban, polls in one
- Strong governance — XWiki SAS (FR) with privacy focus
- Active development — government + EU funding
Integrations
- Document types — pad (Markdown), sheets, slides, kanban, polls, forms
- Authentication — local + SSO via reverse proxy
- Sharing — encrypted link-based with optional password
- API — limited; E2EE constrains programmatic access

- Federation — limited cross-instance support

Tips & operations
- Resource sizing — collaborative apps need decent RAM (4 GB+ for multi-user)
- Block storage grows — encrypted blobs accumulate; size disk
- No password recovery — lost passwords = lost data (E2EE!)
- Backup is encrypted — server backup is just encrypted blobs
- Mind concurrent users — WebSocket connections add overhead
- Educate users on E2EE — share key carefully; password recovery impossible
