I Built a Local-AI Character Forge and a Browser Game Engine on a $100/y VPS (No GPU, No Excuses)

A developer has successfully deployed a 3D character generator and a browser-based game engine on a budget-friendly VPS lacking a dedicated GPU. The project, dubbed CHARFORGE and 3D GAME ENGINE, utilizes clever architectural trade-offs to manage resource constraints. By offloading 3D rendering to the client-side via Three.js and using a queue-based system for AI tasks, the developer ensures the server remains responsive. The system leverages lightweight local AI models, such as Llama 3.2 and SD-Turbo, to handle character identity and garment generation without incurring external API costs. The author emphasizes that success on limited hardware relies on matching model tiers to available resources, implementing robust deployment safety, and optimizing rendering pipelines. This project demonstrates that sophisticated AI-driven applications can thrive on modest infrastructure through disciplined engineering and a focus on efficient, non-blocking workflows.
