Library of Low-Poly 3D Models Built by AI Agents, Ready for Web Games

Web-ready low-poly 3D assets made by AI agents: recolor, resize, remix, export.

In plain English

Polyfork sells simple 3D models like buildings, cars, trees and characters for web games and apps. AI helpers make the models, and automatic checks test each one before it goes in the shop. Buyers can change colours and sizes and download the files for most game tools. AI coding tools can also search the library and pull models in directly.

Step-by-step setup

  1. Pick a product buyers need in bulk and in one style: low-poly 3D models for web games.
  2. Set up AI agents that build each model, plus automatic checks that reject bad ones.
  3. Let buyers tweak colours and sizes and download files for common game tools.
  4. Sell plans or packs; add a connector so AI coding tools can find and use the models.

Realistic income

TrustMRR (checked Nov 5, 2026) shows $5,695 in Stripe-verified revenue over the last 30 days and $20,957 over its tracked history. It showed no active monthly subscriptions, so most sales are one-off payments or credits. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live listing — numbers change.

Risks

  • Revenue swings: TrustMRR showed no active subscriptions, and sales came partly from launch buzz and an XPRIZE win.
  • Quality control matters: broken models hurt trust fast.
  • Free and cheap asset packs are everywhere.
  • Startup cost and time to first dollar are not disclosed.
