Signboard is self-hosted digital signage for cafés, offices, gyms, and shops. Signage SaaS charges per screen, per month, forever — Yodeck is $8/screen/mo, OptiSigns $10, ScreenCloud $20+. Five screens on Yodeck is $480/yr; Signboard is $49 once, and over 3 years that same 5-screen setup saves you $1,391+ versus Yodeck alone.

Pair any screen — smart-TV browser, old tablet, Raspberry Pi in kiosk Chromium — by typing the 6-character code shown on the player page. No player app, no per-device account.

• Content library: image/video upload, embedded web pages, and announcement slides from 5 layout templates (“Closed Friday” in 20 seconds)
• Playlists with drag-to-reorder, per-item duration overrides, and cut/fade transitions
• Server-side dayparting (“Mon–Fri 07:00–11:00 → Breakfast Menu”) evaluated in the screen’s own timezone
• Live health dashboard: online/offline, last seen, currently playing, resolution, player version
• Instant WebSocket updates to affected players, with a 60s polling fallback
• Service-worker offline caching so a dropped connection never blanks a screen
• Emergency takeover: push one slide to every screen instantly, clear with one click
• One SQLite file + uploads folder, zero telemetry

Runs as a Windows desktop app (doubles as a kiosk player) or on a $5 VPS (Docker included).

What’s included:
