KDataForge lets you rebalance and create Satisfactory game content (recipes, items, buildings, gameplay tags, and more) with plain YAML files, no code or editor required.

KDataForge is a reflection-based runtime content editor. Drop .yml files into <GameFolder>/FactoryGame/DataForge/ and it applies them at startup: no C++, no Blueprint, no cooking. It can edit any reflected property on any class default object or data asset, register gameplay tags, generate entirely new items/buildings/recipes/schematics, and patch spawned actors live.

Full grammar, examples for every document type, and task-oriented tutorials live in the documentation.

• Edit any reflected property on any class default object: numbers, texts, arrays, maps, structs, object references
• 22 property operations: set, multiply, clamp, append, remove, sort, copy, and more
• Target class defaults, single data assets, or all assets of a class at once
• Reference classes by their short name (e.g. Desc_Water) instead of the full asset path
• Conditional documents: apply only for certain game versions, installed mods, or existing classes
• Trace every applied change with debug logging: per file (debug: true), per pack, or globally (KDF.Debug 1 / -KDFDebug), each op logged with its before/after values

• Create new items, resources, buildings, recipes, schematics, research trees and unlocks from YAML: no editor, no cooking
• Generated content is savegame-stable: deterministic id-based classes plus a tombstone manifest mean your saves load cleanly even after packs change or disappear
• Rename ids safely with pack redirects: so old saves keep working
• Register existing classes (e.g. hidden schematics from other mods) without generating anything
• Go beyond the preset types with type: class: generate a class from any parent (equipment descriptors, categories, other mods' classes, …), C++ or Blueprint
• Ship your own 2D images (PNG/JPG/TGA/BMP) in a pack and use them as item or building icons: loaded at runtime, no cooking

• Register new gameplay tags at runtime from YAML; add/remove/clear tags on any tag container property
• applyToSpawnedActors: true re-applies your values to every actor instance the moment it spawns: even values that saves or archetypes would normally override

• Group files into packs with a pack.yml manifest (name, version, priority, dependencies) for deterministic load order across packs and files
• DataForge YAML is loaded once during session initialization; restart the session after changing files
• /kdf report prints a full load report with warnings and errors
• Broken files never block loading: you get warnings instead
