01
Offline by design
A service worker caches each release — artwork, images, video, fonts — into versioned storage. The screen only flips versions after every byte is local, and keeps playing through any outage.
Player · Certified tier
Any browser is already a player.
The fastest way onto a TV: open player.canvasrelay.app on anything with Chrome or Edge, pair it with a code, and it's a managed screen — with offline cache and self-recovery, not just a bookmark.

Chrome/Edge kiosk mode is a fully supported CanvasRelay player: offline cache, version-gated updates, watchdog recovery, and health reporting — same promise as the Pi image.
Why the browser player counts as 'real'
02
Self-recovering
An in-page watchdog reloads a stalled render loop, and the player holds your last two good releases so a bad update rolls itself back instead of going black.
03
Managed like hardware
Pairing codes, health heartbeats, offline email alerts, remote reload/clear-cache/diagnostics commands, and proof-of-play logging — all the device management of a dedicated player.
04
Great hardware it's happy on
A Windows mini PC behind the TV, a Chromebox, an Intel NUC, a retired laptop. If it runs Chrome or Edge and stays plugged in, it's a signage player now.
05
Kiosk mode in one flag
Boot your box with Chrome's --kiosk flag pointed at the player URL and it behaves exactly like an appliance — fullscreen, no chrome, auto-start.
06
Preview-only devices, honestly labeled
Smart-TV built-in browsers and phones render the player but aren't supported for unattended use. We'll tell you that up front instead of letting you find out at 9pm on a Saturday.
Questions, answered
01What do I need to run the browser player?+
Any device that can open a current version of Chrome or Edge fullscreen — a Windows mini PC, a Mac mini, a Chromebox, an old laptop, a Pi with a desktop. Point it at player.canvasrelay.app, pair it, done.
02Does the browser player work offline?+
Yes — it's a full player, not a web page that breaks without Wi-Fi. A service worker caches every release on the device; screens keep playing through outages and reboot straight back into your content.
03How is this different from just opening my board in a tab?+
The player is a managed kiosk: it pairs to your organization, follows published releases atomically, heartbeats its health to your dashboard, recovers itself from stalls, and applies announcements within a minute.
04What about my smart TV's built-in browser?+
Honestly: we label those Preview-only. Smart-TV browsers are slow to update and unreliable as 24/7 players — fine for checking a board, not for unattended playback. A $30 Fire Stick or any mini PC is the better answer.
