Building Forge — an AI engine for creating explorable 3D worlds

Hey everyone — I'm a solo developer, and this is my first post here.

For the past few months, I've been building Forge. The idea is simple: describe an environment in plain language, and Forge turns it into an explorable 3D world.

Not an image. Not a single 3D model. An actual environment you can walk around and interact with.

I originally started Forge as a personal challenge to see if I could build something genuinely different. But as I worked on it, I started seeing a much bigger possibility — a tool that could let people turn their ideas into worlds without having to build every part of the environment manually.

I'm still early, and there is a lot left to solve. I'm currently focused on improving the visuals, performance, and getting the first real users to try it.

I want to use Indie Hackers to document the process honestly — what works, what breaks, what I learn, and how Forge evolves.

If you're a game developer, 3D creator, indie hacker, or just interested in generative 3D, I'd love to hear from you.

What would you build if you could describe a 3D world instead of building it piece by piece?
