What Signet is
Signet is a free, open-source digital signage system for managing content across multiple screens. Its dashboard shows whether screens are online or offline and what each is playing. Image playlists can be reused, assigned slide durations, and reordered by dragging. A visual scheduler places content on specific screens across days and weeks, with high-priority events overriding default content. The media library supports PNG, JPG, GIF, and SVG files. Physical screens pair through a PIN, linking them to an account without exposing credentials. Signet is offered as a hosted web service or can be self-hosted on a user’s Firebase project. The maker presents self-hosting as a way to own the data and says there is no tracking or hidden telemetry. Repository instructions use Google sign-in through Firebase Authentication and require a Firebase account, Node.js v20 or higher, and npm. Firebase Cloud Functions may require the Blaze pay-as-you-go plan, although the guide says its free tier is likely sufficient for this project’s usage. The Free plan costs nothing.
