Rent Rust Server

Using Rust+ With Your Server

Pair the official Rust+ companion app with your server: live map, team chat, smart devices — and what the app port does.

Last updated July 13, 2026 · RespawnHost

What is Rust+?

Rust+ is Facepunch’s official, free companion app for iOS and Android. Paired with your server it offers:

  • Live map of the server with teammates, vending machines and events
  • Server status: player count, game time, online teammates
  • Team chat — synced with the in-game team chat
  • Smart devices: toggle smart switches remotely, push notifications from smart alarms

Does Rust+ work on rented servers?

Yes. The companion server is part of every Rust dedicated server and enabled by default — on community and modded servers alike. The only requirement is that the app port is reachable from outside: by default it sits 67 ports above the game or RCON port (so 28082 with standard ports). At RespawnHost the app port is assigned and opened automatically — nothing to configure.

How players pair

  1. Get Rust+ from the App Store / Play Store and sign in with your Steam account.
  2. Log in to your server in-game.
  3. Open the Rust+ menu in-game (pairing option) and pair the server — each player decides individually whether to receive the server’s notifications.

Afterwards the server appears in the app; smart devices (switches, alarms) pair with the app when placed or via their menu.

Disabling Rust+

Don’t want to offer Rust+ on your server (e.g. for hardcore-style gameplay)? Set the startup variable app.port -1 — that turns the companion server off.

Note

The companion.id file in the server directory is your server's Rust+ identity. Don't copy it to other servers and don't share it — it breaks pairing otherwise.

Frequently asked questions

The app can’t find my server — what now? First check that the server is running and that you paired in-game (pairing only works in-game, not from the app). Facepunch automatically tests the app port’s reachability — if the test keeps failing, Rust+ gets disabled server-side.

Does Rust+ cost anything? No, the app is free.
