> img-forge: production AI image generation for agents, apps, and pipelines — 11 models, one endpoint, flat credits, REST + MCP. Plus governed code scaffolds in every plan.

## What This Is

Stackbilder (stackbilder.com) is the home of **img-forge**, a production AI image generation API for agents, apps, and pipelines: 11 models across 3 quality tiers (SDXL, FLUX, Leonardo, Gemini), one endpoint, flat credits, seed-locked character consistency, and inpainting. It ships as a REST API and a dedicated MCP server (imgforge-mcp.stackbilder.com) that autonomous agents call unattended. Every plan also includes governed code scaffolds — STRIDE threat models, architectural decision records (ADRs), integration test plans, and production-ready Cloudflare Workers project structure.

## Core Value Proposition

Ship image assets like you ship code. One endpoint routes 11 models — 4-second SDXL drafts to Gemini ultra — with flat credits and MCP tools your agents call unattended. And when you build the app around those assets, Stackbilder's governed scaffolds give it architecture, threat models, ADRs, and test plans before the codebase becomes a haunted house.
