ComfyUI workflows for product image generation

Build reproducible image pipelines for SaaS landing pages without Midjourney subscriptions.

TL;DR

ComfyUI with SDXL or Flux gives indie hackers full control over product mockups and marketing assets at ~$0.02/image on a $20/mo GPU VPS — 10× cheaper than subscription tools for teams generating 500+ images/month.

ComfyUI changed how indie hackers produce marketing assets. Instead of $30/mo Midjourney subscriptions or stock photo hunts, you build reproducible node graphs that generate on-brand product mockups, hero images, and social creatives at pennies per render.

Frequently asked questions

Flux or SDXL for SaaS landing page images?
Flux for photorealism and text-in-image. SDXL for speed on consumer GPUs. Most indie teams use Flux at 1024px for heroes, SDXL for social thumbnails.
Can designers without coding skills use ComfyUI?
Yes — the node UI is visual. Start with community workflows on OpenArt. Coding helps for automation and API integration, not basic generation.
How do I keep generated assets on-brand?
Train a LoRA on 15–30 brand screenshots. Use ControlNet with wireframes. Store workflow JSON in git for reproducibility.
