Open Forge
For game jams & indie devs

Design, balance & ship gameplay systems faster.

Forge is a visual stat designer for data-driven games. Tune health, damage, buffs and combat formulas in real time, then export clean JSON for Godot and Unity.

Stop hardcoding stat values

Tweaking numbers across scripts, scenes and prefabs kills momentum. Forge centralizes your stats and modifiers so designers can iterate without touching engine code.

What you can build

Character classes

Knight, Mage, Boss — define archetypes with min/base/max stats.

Core stats

HP, damage, stamina, mana, defense, crit, attack & movement speed and custom stats.

Buffs & modifiers

Additive, percent, multiplicative — with conditional triggers.

RPG progression

Model leveling curves with bounds, clamping and live previews.

Weapons & enemies

Compose entities from reusable stats and exported templates.

Damage formulas

(base + Σadd) × (1 + Σ%) × Π mult — clamped to bounds.
