About SeedSeer
From ThunderstoreReveals the world seed of any Valheim world — client-side (spawn message, seed console command, log file), even on servers running no mods. Optional server mode adds console/log output and a /seed chat command (optionally admin-only).
SeedSeer
A tiny utility that reveals the world seed of any Valheim world — client-side, with an optional dedicated server mode.
SeedSeer answers one question every Valheim player and server admin eventually faces: "What seed is this world running?" Install it on your game client and you'll see the seed of any world you join — including dedicated servers you don't control — because every Valheim client receives the world seed to generate terrain locally. Optionally install it on your dedicated server too, and your players can request the seed in chat with /seed.
🌟 Features
🌱 Client-Side Seed Reveal (Works on Any Server)
- Spawn Message: The first time your character spawns into a world, the seed appears as an in-game message (e.g.,
[SeedSeer] World seed: "MyWorldSeed" (hash: -123456789)). Toggle withShowOnSpawnin config. seedConsole Command: Typeseedin the F5 console at any time to print the current world's seed to the console and HUD.- Dedicated Server Friendly: Connecting to a dedicated server? Valheim sends the server's world seed to every client — SeedSeer displays it, even if the server runs no mods at all.
- Log Output: The seed is also written to
BepInEx/LogOutput.logon every world load.
🖥️ Optional Dedicated Server Mode
- Server Console & Log: When installed on a dedicated server, the seed is printed via
ZLogto the server console andLogOutput.logat world load. /seedChat Command: Any player can type/seed(or!seed) in chat and receive the world seed back as a private whisper — no console access needed.- Optional Admin-Only Restriction: Set
AdminOnlyCommand = truein config to limit/seedreplies to players inadminlist.txt(default: off, everyone can request). -seedLaunch Argument Verification: If the server is started with a-seedargument, its value is logged at plugin load so you can confirm the server received the seed you intended.- Audited: Every
/seedreply is recorded in the server log with the requesting player's name.
