End-to-end encrypted collaboration suite
CryptPad is an open-source end-to-end encrypted collaboration suite that provides real-time document editing, spreadsheets, presentations, kanban boards, whiteboards, and forms without the server ever accessing user content. Built as a privacy-first alternative to Google Workspace, CryptPad encrypts all data client-side so neither administrators nor attackers can read stored documents. It supports team drives, access control, and self-hosting.
