What is CryptPad?
CryptPad is an open-source collaboration platform that stores and transmits all data with end-to-end encryption. The server operator sees no plaintext, no metadata about content, no usage behaviour. This sets CryptPad apart from cloud services such as Google Docs or Notion, which process content to improve their products. The platform can be self-hosted, and whoever controls the infrastructure controls the data entirely.
Core features
- End-to-end encryption for all document types, including text documents, spreadsheets and presentations
- Real-time collaboration on shared documents, without the server being able to read the content
- Encrypted file storage for keeping sensitive files secure
- Self-hosting option on your own infrastructure, with no dependency on third-party providers
- No tracking, no data sales, including on the hosted version at cryptpad.org
Who is CryptPad for?
Development teams, NGOs and organisations that are legally or ethically unable (or unwilling) to store documents in external clouds. Activists and journalists who need to collaborate confidentially use CryptPad for its encryption. Teams without their own infrastructure can use the hosted instance at cryptpad.org. CryptPad delivers its full value on a self-operated server, though. Without Linux knowledge and Docker experience, the setup will fail at the deployment stage. Anyone who applies regular updates and manages backups also takes on responsibility for data security.
Context & alternatives
CryptPad belongs to the category of collaborative knowledge tools, but its focus on encryption sets it apart from competitors such as Notion, Confluence or HedgeDoc. HedgeDoc also offers collaborative writing as an open-source solution, but without end-to-end encryption. Nextcloud with the relevant apps comes close to CryptPad in its self-hosting approach, but does not encrypt content end-to-end on the server side by default. For those who treat privacy not as a feature but as a fundamental technical requirement, CryptPad is one of the few platforms that actually implements this at the architectural level.
