Nextcloud

Description

Nextcloud is an open-source content-collaboration platform and a self-hostable alternative to Google Drive, Dropbox, and Microsoft 365. It starts with file sync and share and extends into calendar, contacts, mail, chat, video calls, and collaborative office documents, so a team can replace a stack of SaaS tools with one platform running on hardware they control. A large app ecosystem and granular administration make it suitable for home labs and regulated enterprises alike.

Features

• Groupware: Calendar, contacts, and mail with CalDAV/CardDAV, plus Deck for kanban boards.
• Real-time collaboration: Edit documents together with the built-in Nextcloud Office (Collabora / OnlyOffice).
