Caracal fleet

CARACAL Fleet is a self-hosted control center for CARACAL digital signage. Monitor, fill, schedule, install and update every screen from one web interface, with one docker compose up. No subscription, no per-screen fees, no cloud.

Watch every screen

Live state of every screen: online status, CPU, RAM, disk, temperature and what is playing right now, plus a Needs attention list explaining each issue Screen wall with a live view of all screens, a map of locations and 24-hour / 7-day availability graphs Alerts by e-mail, Microsoft Teams, Slack, Discord, Telegram, ntfy or webhook, with “resolved” messages and maintenance muting Proof of play with charts and CSV export, plus monthly PDF reports Diagnostics for black screens, one-click reinstall and an SSH console right in the browser

Content that just works, even behind a login

Playlists with web pages, images, videos, Grafana collections, PDFs and PowerPoint/Word documents Automatic sign-in to websites behind a login form or the browser’s HTTP log-in pop-up; credentials are stored encrypted on the screen only and never kept on the hub Widgets: clock, weather, RSS news, CSV/Google Sheets tables, calendars and meeting-room status from Microsoft 365 or Google, QR codes and tickers IP cameras (RTSP, HTTP, ONVIF auto-discovery) in grids of up to 9 Content with validity, so a weekend offer appears and disappears by itself On-screen notifications from Grafana, Alertmanager, Uptime Kuma, Zabbix and ticketing tools, and one-click emergency messages for all or selected screens

Run the whole fleet

Global playlists deployed to many screens, with 50 kept versions and a per-device preview of changes Schedules by time and weekday, screen hours with HDMI-CEC power saving and timed actions Approval workflow, shared media library with Replace everywhere and node templates Groups, locations, labels and multi-tenant customers for companies running screens for others Commands reach a screen within a second; screens can sit behind NAT

Zero-touch install and safe updates

Prepare an SD card for Raspberry Pi, a USB stick for a PC (Alpine or Ubuntu), use one install command or discover devices in the network and install over SSH Updates with automatic rollback, staged rollouts to pilot nodes first Air-gapped networks: Fleet can be the only download source for packages, Docker and CARACAL Fleet updates itself in one click

Enterprise-ready security Thirteen permissions in custom roles scoped to locations, groups or devices; two-factor sign-in, single sign-on through OpenID Connect (Entra ID, Google, Keycloak, Authentik); audit log; REST API and signed webhooks; encrypted off-site backups to S3, WebDAV, SFTP, SMB, NFS or any rclone cloud.
