A digital-signage rotator that lives in a single HTML file — no install, no account, no internet after the first load. Turn any spare screen into a maintained display: image and text slides, adjustable rotation and transitions, a clock overlay, all saved to that screen's browser. Free to use; a one-time CA$59 Pro add-on turns it into a real signage system — live weather, RSS, scheduling, and synchronized multi-screen playback.
This is the actual tool — not a screenshot. The frame below loads the SignLead landing straight from the server. Scroll it, then jump into the full editor below.

One HTML file — editor and player in the same document. Slides, media,
settings and analytics live in localStorage / IndexedDB on that
screen. The free tier makes zero network requests; put it on a USB stick and it runs with the
Wi-Fi off, the same on Windows, macOS, ChromeOS or a tablet.

The real editor, loaded live. Add a slide, set the rotation, then open
the same file with #/play on the end to see the kiosk player. Nothing is sent
anywhere — edits live only in this browser and clear when you do. Best experienced in its own
tab.
From a blank screen to a running lobby display in a few minutes — no signage CMS to learn, no account to create.
Drag in an image or write a text slide — headline, body, an optional bullet list, your own colours.
A global interval plus a per-slide duration override, and a transition — fade, slide, zoom or cut.
Open the same file with #/play on the end, press F, and set the
browser to launch that address on boot.
Copy the file to every screen at your site — the licence is per organisation, not per device.
The free single file covers a complete lobby display. Your Pro download is a pre-licensed copy of the same file — nothing to paste in.
Drag-and-drop images (stored locally), plus text slides with a headline, body, bullet list and custom colours.
A global interval plus a per-slide override; fade, slide, zoom or cut, with adjustable speed.
Full-screen, keyboard-driven, auto-restarts on load — built for a screen left running all day.
A clock/date overlay in any corner, four theme presets or fully custom colours, and a progress indicator.
The free tier makes no network requests at all — everything stays local to that screen.
Export the whole configuration to JSON, optionally with media, and import it on another screen.
Current conditions from Open-Meteo (no API key), plus RSS feeds as a scrolling ticker or a headlines slide.
Bind a deck to specific weekdays and a time window, with priority and optional campaign dates.
One controller drives every follower in lock-step, plus an instant emergency-alert override.
An uploaded video or a pasted YouTube link, or embed a live dashboard, menu or any URL.
On-device QR codes for giving, check-in or Wi-Fi, and a large countdown to any date and time.
Every impression logged with a CSV export, and every synced screen reachable from the editor's Screens list.
Digital-signage software is almost always billed per screen, per month. Here is where a single-file tool lands next to them.
