// EDITOR'S TAKE
No single project replaces the bundle. CryptPad comes closest to the collaborative web suite, with encrypted docs, sheets and slides that several people can edit at once, while onlyoffice-docs beats it badly on Microsoft format fidelity if you pair it with a file platform. Tuta only fills the mail and calendar half, and LibreOffice is a desktop suite, not a shared workspace.
