Baldur's Gate 3 Modding Tools Guide 2026

BG3 modding is split between two platforms: Nexus Mods (traditional, larger library) and mod.io (official, integrated). Here's how to navigate both.

🔧 BG3 Script Extender (Norbyte)

Enables script-heavy mods that the official mod.io platform doesn't support. Required for class expansions, combat overhauls, and advanced mods. BG3MM has a one-click installer. 5M+ downloads.

📦 BG3 Mod Manager (BG3MM) vs Larian In-Game

BG3MM: Best for power users. Supports Nexus Mods, drag-drop load order, Script Extender installer, conflict detection. Larian In-Game: Best for casual users. Built into the game since Patch 7. Curated mod.io catalog. Only option for console players.

📋 Which mod platform?

Nexus Mods: Larger library (11,000+), older mods, requires BG3MM. mod.io (official): Curated, safer, works on all platforms including console. Most new mods release on both.
