CryptPad – encrypted collaborative office suite

CryptPad is a browser-based productivity and collaboration suite that uses end-to-end encryption to protect documents and other content. It enables individuals and teams to work together on shared material without giving the hosting server access to the unencrypted document contents.

The software offers a collection of office and organisational applications, including document editors, spreadsheets, presentations and collaborative planning tools. Its document, spreadsheet and presentation editors incorporate ONLYOFFICE technology within CryptPad’s encrypted collaboration system.

CryptPad can be used through a hosted service or deployed on an organisation’s own infrastructure. Its privacy-focused design makes it particularly appealing to teams that need collaborative editing while retaining control over access to sensitive information.

This is free and open source software.
