Same, live updating didn't work but a page refresh did. I don't know much about websockets, but FWIW this request is still pending:

    Request URL: wss://ws.endpoints.dev/?token=redacted
    Request Method: GET
    Status Code: 101 Switching Protocols

it's normal for websockets to show as pending in devtools. Check the Messages tab

Fixing the real time update would be my only immediate feedback. Outside of that, this is a pretty nice app

Found the bug! Live updating should be working now

Live updating also not working for me. I do have uMatrix installed but I whitelisted your whole site for each column.
