Rust Player Track — Pair Helper by Rust Player Track

The Rust Player Track Pair Helper bridges Facepunch's Rust+ Steam login flow into the rustplayertrack.app dashboard so you can pair Rust game servers from any modern browser.

Two production hosts. One development host. That's it.

• companion-rust.facepunch.com — to capture the SteamID and AuthToken Facepunch's sign-in page produces.
• rustplayertrack.app (and its preview subdomains) — to hand those values back to your dashboard tab.
• http://localhost:5173/* — development-only. The maintainer's local Vite dev server runs on this port; the entry exists so the same extension build can be loaded against a local copy of rustplayertrack.app during development. Not reachable from your machine unless you happen to be running our dev server on the same host.

The extension does not:

• Store credentials. Ever. Heap-only flow, no extension storage, no localStorage, no IndexedDB, no cookies.
• Request broad permissions — no all_urls, no cookies, no storage, no webRequest.

Two scoped capabilities it does use, and why:

• A background script that acts purely as a message relay: it re-broadcasts the captured pairing message from the Facepunch tab to your open rustplayertrack.app tab (content scripts cannot message each other directly). Event-driven, no state, no network requests of its own.
• The tabs permission, solely so that relay can find your open rustplayertrack.app tab by URL (tabs.query + tabs.sendMessage against rustplayertrack.app/localhost patterns only). It never enumerates, reads, or modifies any other tab.

Why does this exist?

Facepunch's Rust+ Steam sign-in is designed for their mobile app and only delivers credentials via a mobile-only API (ReactNativeWebView.postMessage). This extension supplies that API on a normal browser, capturing the credentials Facepunch's own page hands to it.
