Pterodactyl Egg Server-Side Modpack

A lightweight Valheim dedicated server performance and networking modpack built for the Pterodactyl BepInEx Egg.

Designed as a drop-in base for virtually any dedicated Valheim server, including completely vanilla servers. Players do not need to install anything.

What does it do?

This pack combines FiresGhettoNetworking and FiresSteamworksPatcher to improve Valheim's dedicated-server networking, buffering, queues, send rates, and related server performance.

Most improvements work entirely server-side and are transparent to vanilla clients.

Players who also install the networking mods client-side get additional benefits, including client-side tuning and features negotiated between the server and client.

Additional Mods

• ValheimPerformanceOptimizations — reduces CPU overhead and unnecessary allocations across several of Valheim's systems, improving performance without intentionally changing vanilla gameplay.
• LocalizationCache — caches localization lookups to reduce unnecessary repeated work and improve performance.
• LogKeeper — keeps timestamped backups of BepInEx logs across server restarts, making crashes and other problems easier to diagnose.
• MaxPlayerCount — makes Valheim's normally hardcoded 10-player server limit configurable.
• Unshamed — keeps legitimate Valheim achievements working for players who optionally install the pack client-side.

See the individual mod pages for full feature lists, configuration options, and technical details.

Pterodactyl Installation

The official Valheim BepInEx Pterodactyl Egg supports automatic Thunderstore modpack installation.

Then reinstall the server.

The dependency string includes the modpack version. When updating this pack, update the string in Pterodactyl and reinstall the server.

Why this pack?

If you're running a Valheim dedicated server, there's little reason not to use it.

It improves the server without requiring players to mod their game, making it useful whether you're running vanilla Valheim, a lightly modded server, or a full modpack.

Use it as the base, then add whatever other server or gameplay mods you want.
