What is it?

Spacepad is a room display app for offices. It shows whether a meeting room is free or busy in real time, with calendars from Google Workspace, Microsoft 365 (Outlook) and any CalDAV provider such as Nextcloud or iCloud feeding into it. It is typically run on a tablet mounted outside a meeting space.

Displays can be used to book a room directly from the screen with preset 15, 30 or 60 minute durations or custom time slots, check in to reserved meetings, and cancel current meetings. Multi-room overview boards offer card, table or grid layouts, and each display can show the full day's schedule. Privacy controls can hide meeting titles.

Workspaces group displays, calendars and boards, and can be shared with team members under role-based access. The project can be self-hosted with Docker, and native iOS and Android apps are built with Flutter. A hosted cloud version is also offered.
