FAQ
Common questions about TerrariaModder.
How is this different from tModLoader?
They're completely separate tools. tModLoader is its own modified version of Terraria with a separate Steam install and executable that replaces the game binary to load mods. Because it's a full recompile, updates can take months after a new Terraria version drops.
TerrariaModder is a lightweight framework that works on the original vanilla game, patching it at runtime so nothing is replaced or recompiled. This means it can be updated quickly for compatibility with major game updates. They don't share mods, configs, or code.
TerrariaModder is for players who want or need to stay on vanilla — speedrunners who need the unmodified game, server owners who stay vanilla for accessibility, players with too much built in vanilla to migrate, or anyone who just wants non-gameplay mods like smoother FPS or widescreen support. If you want mods on the original game, TerrariaModder gives you that option.
Does it modify my Terraria files?
No. All patches are applied in memory at launch and are completely gone when you close the game. Your Terraria installation is never touched.
Does it work on Terraria 1.4.5?
Yes. TerrariaModder was built specifically to mod the current vanilla version.
Can I use it alongside tModLoader?
Yes. They're completely independent — different executables, different mod formats, different ecosystems. Having one installed doesn't affect the other. You just launch whichever one you want to play.
What mods are available?
There's a growing collection of quality-of-life and utility mods: AutoBuffs, QuickKeys, StorageHub, AdminPanel, ItemSpawner, PetChests, WhipStacking, FpsUnlocked, and more. See the Mods page for the full list. All install in one click via the Vault.
What is the Vault?
The Vault is the official mod manager for TerrariaModder. It finds your Terraria install, sets up the framework, lets you browse and install mods, keeps everything updated, and launches the game. It's the recommended way to get started — download it on Nexus.
Can I make my own mod?
Yes. TerrariaModder has a C# mod API with Harmony patching, a config system, keybind registration, events, and UI rendering built in. The Dev Docs cover everything you need to ship a mod.
Does it work on Mac or Linux?
Currently Windows only. The framework targets .NET Framework 4.8. Mac and Linux support is on the roadmap.
