At a Glance:
Anthias is an open-source digital signage platform designed to run on Raspberry Pi devices and PCs, supporting images, web pages, and video playback with a web-based management dashboard.
Overview:
Anthias is an open-source digital signage solution that transforms Raspberry Pi devices and PCs into display endpoints managed through a centralized web dashboard. The platform handles content scheduling, asset management, and playback across connected screens. Formerly known as Screenly OSE, Anthias was rebranded to distinguish it from the commercial Screenly product. It supports Debian-based Armbian distributions on generic 64-bit ARM single-board computers on a best-effort basis, with tested boards including Rock Pi 4, Orange Pi 5, and Banana Pi M5. The system uses Docker for deployment and provides a scheduler, asset library, and viewer component for rendering content.
Key Decision Points:
Hardware compatibility: Runs on Raspberry Pi devices, generic 64-bit ARM SBCs with Debian-based Armbian, and PC hardware, with varying video playback performance depending on the board.
Video playback limitations: Hardware-accelerated video decoding is not yet implemented on non-Raspberry Pi ARM boards, meaning 720p video plays reasonably but 1080p can stutter and 4K is not suitable on those devices.
Boot experience on ARM SBCs: Non-Pi boards do not display the Plymouth boot splash due to U-Boot limitations, showing kernel boot log output instead until content playback begins.
OS compatibility constraints: The installer only supports Debian-based Armbian images on ARM SBCs, meaning Ubuntu-based Armbian downloads will fail during installation.
Core Features:
Web-based dashboard: Provides centralized management of content scheduling, asset libraries, and connected displays.
Asset library: Stores and organizes digital signage content including images, web pages, and videos.
Content scheduler: Controls when and how assets are displayed across connected screens.
Viewer application: Renders scheduled content on each display endpoint.
Docker-based deployment: Uses Docker containers for installation and runtime on supported platforms.
WebView support: Can display web-based content as part of digital signage playlists.
Use Cases:
Deploying digital signage displays on existing Raspberry Pi hardware without commercial licensing costs.
Running informational displays, dashboards, or announcement screens in maker spaces, labs, or community venues.
Experimenting with or evaluating digital signage software before committing to a commercial platform.
Open-Source Alternative Value:
Anthias functions as an open-source alternative to commercial digital signage platforms, with its origins as the community edition of Screenly. Users can self-host the complete stack on Raspberry Pi, generic ARM single-board computers, or PC hardware using Docker, retaining control over content, scheduling, and data without subscription fees. The project supports multiple hardware targets beyond Raspberry Pi, though with documented performance trade-offs, allowing users to choose boards based on their content needs and budget.
