Open source · built by an AI dev loop · forgeax.github.io

Your personal game studio.

ForgeaX is an AI-native game development studio — turn your ideas into playable games while AI writes the engine code, hot-reloading live in your browser. More unusually: the engine and platform themselves are written almost entirely by AI, line by line, in a self-running development loop — and its day-by-day self-build is logged in the changelog, a kind of long-term development memory for the AI.

Let smaller teams make bigger games.

Many ways to create

Chat, a visual editor, and image / video input later — express your ideas whatever way suits you.

Agentic by design

Agents plan, design and write the engine code; you set requirements and review.

Live hot-reload

Every change lands in the preview instantly — what you say is what you play.

Real ECS engine

A genuine entity-component-system engine with dual-RHI rendering, in a browser studio.

AI-native gameplay

Not just making games with AI — also building AI into the play itself: intelligent NPCs, generative content, interactive AI experiences.

Self-evolving dev loop

The ForgeaX closed loop — a requirements → build → verify pipeline that learns from its own feedback and grows steadier over time.

Runs in the browser

WebGPU-powered, web and desktop on one stack, up and running in a minute.

Open source

Apache 2.0 — free to fork, use, ship and build commercially with.

Bring your own AI agent

The brain lives in ForgeaX, the engine is yours
1

ForgeaX supplies the brain

A homegrown orchestration kernel plus the Forge persona: a multi-agent team that plans, delegates, writes the engine code and reports back.

2

Your local CLI supplies the engine

Wire in the coding agent you already pay for (or a plain API key) as the reasoning backend — no second AI bill.

3

Switch in one place, anytime

Pick a provider in the panel to swap the engine; your personas and workflows stay exactly the same, with no code to rewrite.

No vendor lock-in — use whichever AI suits you, and switch anytime.
