About SeedSeer

From Thunderstore

Reveals 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 with ShowOnSpawn in config.
  • seed Console Command: Type seed in 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.log on every world load.

🖥️ Optional Dedicated Server Mode

  • Server Console & Log: When installed on a dedicated server, the seed is printed via ZLog to the server console and LogOutput.log at world load.
  • /seed Chat 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 = true in config to limit /seed replies to players in adminlist.txt (default: off, everyone can request).
  • -seed Launch Argument Verification: If the server is started with a -seed argument, its value is logged at plugin load so you can confirm the server received the seed you intended.
  • Audited: Every /seed reply is recorded in the server log with the requesting player's name.

⚙️ Configuration

All settings live in BepInEx/config/com.jubaroo.seedseer.cfg:

  • ShowOnSpawn (Default: true) — Client-side: show the world seed as an in-game message on first spawn into a world.
  • AdminOnlyCommand (Default: false) — Server-side: restrict /seed chat command replies to players listed in adminlist.txt.

📦 Installation Instructions

Prerequisite: You must have BepInExPack Valheim (v5.4.2202 or later) installed before installing SeedSeer.

Using a Mod Manager (Recommended):

  1. Open your preferred Valheim mod manager.
  2. Click the Install with Mod Manager button on this page, or search for "SeedSeer" within the manager's download interface.
  3. Ensure BepInEx is enabled.
  4. Launch the game — the seed appears when you spawn into a world.

Manual Installation (Client):

  1. Click the Manual Download button on this page.
  2. Extract the downloaded .zip archive.
  3. Move the SeedSeer.dll file into your <Valheim>\BepInEx\plugins\SeedSeer\ folder.
  4. Launch the game!

Manual Installation (Dedicated Server — optional):

  1. Extract the downloaded .zip archive.
  2. Move the SeedSeer.dll file into your dedicated server's BepInEx/plugins/SeedSeer/ folder.
  3. Start the server — the seed is printed to the console at world load, and players can use /seed in chat.

🌐 Compatibility & Multiplayer

  • No Server Required: The client-side reveal works on vanilla and modded dedicated servers alike — the server does not need SeedSeer installed.
  • No Client Required: If you only install it on your dedicated server, players need nothing; they can still request the seed via /seed chat.
  • Gameplay Safe: Purely informational — does not alter gameplay, world generation, or network traffic.
  • No Dependencies: Requires nothing beyond BepInEx.
