Workflows de ComfyUI para generación de imágenes de producto
Construye pipelines de imagen reproducibles para landing pages SaaS sin suscripciones a Midjourney.
TL;DR
ComfyUI con SDXL o Flux da a los indie hackers control total sobre mockups y assets de marketing a ~0,02 $/imagen en un VPS GPU de 20 $/mes — 10× más barato que herramientas por suscripción para equipos que generan 500+ imágenes/mes.
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.

View original →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.
