Any event page can embed a ShowUp event with one tag:
<script src="…/widget/widget.js" data-event="EVENT.testnet"></script>.
Event data comes from live testnet RPC view calls. The quote is a live 1Click dry quote.
Add ?relayer=http://localhost:3030 (with pnpm relayer running) to cancel gaslessly, or ?event=<account> to show another event.
Hosted demo (NEAR testnet). Sign in with a Meteor testnet wallet. MyNearWallet now answers "MyNearWallet can't connect to apps anymore" to new app connections (seen 9 Nov 2026), so use Meteor. No gasless relayer runs here, so Cancel and door Check in are signed by your own wallet (about 0.00025 testnet NEAR gas). For the gasless path run the repo locally with pnpm relayer. ?event=<account> shows another event.
