Dash on e-ink.
The display page is plain HTML with no JavaScript, so almost any e-ink browser can render it. That is not the interesting question. The interesting question is whether the device will stay awake, and on most of them the answer is no.

What works
| Device | Browser | Stays awake | Verdict |
|---|---|---|---|
| Onyx Boox | Full Android browser | Yes | Best e-ink option |
| Kindle | Experimental browser | No | Glance device |
| Kobo | Beta browser | No | Glance device |
| PocketBook | Built in | No | Glance device |
| Nook GlowLight | Hidden, model-dependent | No | Try it |
| reMarkable | None | — | Not supported |
"Glance device" means tap to wake and the numbers are current within a second or two. It is genuinely useful. It is not a wall display.
The detail
Boox runs Android, so it has a real Chromium browser and real settings. It is the only e-ink family that does the always-on version properly.
Browser-capable models only. Sleeps after about ten minutes with no supported way to stop it. Full Kindle guide.
Most models hide a browser under Beta Features. It is rough, but it renders a page this simple fine.
A browser ships on most models and is easier to reach than Kindle’s.
Barnes & Noble does not advertise a browser. Several models have one reachable through a trick, and it varies by model and firmware. Worth ten minutes to find out, not worth buying a Nook for.
reMarkable ships no browser at all, and that is deliberate: it is the point of the product. There is nothing on the device that can open a URL, so Dash cannot run on a stock one.
If you are buying one for this
Get an Onyx Boox. It is the only one here that runs a real browser on a real operating system, which means you can set the screen timeout to never and leave it. On a Boox: open the display link, set Auto-sleep and Auto-power-off to Never in Settings, keep it on a charger, and turn on full refresh if you see ghosting.
Why the display looks so plain
That is the e-ink brief, not a shortcut. Pure black on white with no greys means no ghosting between refreshes. No colour carries meaning. No web fonts, no JavaScript, no animation. It is designed for the worst screen in the list and simply looks crisp on better ones.
Browserless devices like reMarkable would need a different mechanism. Dash serving a rendered image that the device pulls, rather than a page it renders. That is not built. If you end up wanting it, it is also what a jailbroken always-on Kindle would use, and kindle-for-whoop proves the mechanism today: WHOOP-only, self-hosted, screensaver swapped for the dashboard.
Other screens
Everything else Dash is set up for: a spare monitor, an iPad, an old iPhone.
