For server owners
How we track players on your server
One small server mod checks in-game that players really reached your goal. It works on vanilla Rust: drop one file into your HarmonyMods folder, no mod loader needed. It doesn't change gameplay, doesn't touch your player count and gives no items.
Data flow
From your server to a verified goal
Your Rust server
SpawnBoost.dll

Watches only players who pressed Start on your offer.
In transit
Signed progress report

Queued on disk and resent if SpawnBoost can't be reached.

Verify & pay
Goal verified → reward approved
You pay only for verified goals. Unused budget is refunded.
Install and pair
- 1. Copy one file. Put
SpawnBoost.dllinto your server'sHarmonyMods/folder. On a hosting panel, upload it there with the file manager. Harmony loading is built into the Rust server. - 2. Start the server. The console prints a 6-digit pairing code.
- 3. Enter the code on SpawnBoost under My servers → Add server. The console confirms the pairing and the server key is saved automatically.
Players who started your offer can type /sb in chat to see their own progress. Only they see the reply.
What counts as playing
A minute counts only when the player is alive, moved or looked around, and did something (gathered, built, crafted, looted, fought or chatted) in the last five minutes. Standing in one spot doing nothing is AFK and never counts, and nobody can collect more active minutes than real minutes.
What the mod sends
- Join and leave times of players who pressed Start on your offer, by SteamID64
- Active minutes: alive, moving or looking around, and doing something in the last 5 minutes
- Goal events: Tool Cupboards placed (and still standing 30 minutes later), resources gathered, items crafted, building upgrades, crates looted
- Anti-cheat statistics, such as how varied the movement was
- Once a minute: server name, player count, map, server FPS and mod version (a heartbeat)
What it never sends
- IP addresses: only keyed hashes, used to catch one person on several accounts
- Player names, chat text, inventories or exact positions
- Anything about players who didn't start one of your offers
- Commands: the mod never runs commands it receives from the internet
Light on your server
All network and disk work runs off the game's main thread. The mod tracks only players who started your offer; for everyone else it does one quick lookup when they gather, build or loot, and that's it.
Safe by design
Every report is signed with your server's key and sent over HTTPS. If heartbeats stop for more than five minutes, your campaigns pause automatically and players' deadlines are extended.
