Diagnostics for the provider
Subscription report
Paste the link from the app and the report opens right in your browser. It rides in the address fragment, which never leaves for a server, and this page makes no network request at all.
Reveal the node names
The node-NN aliases are anonymous on purpose. Paste the body of the subscription itself — a Clash/mihomo config or its base64 — and the page maps the flagged nodes back to real names. Parsing runs only in the browser: no network request, the link is never opened.
