Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Stable Diffusion

Generated images have lower resolution and quality at non-standard dimensions
Struggles with complex multi-object prompts and text generation
Poor rendering of human hands, limbs, and faces due to training data limitations
Trained primarily on English-language descriptions, reinforcing Western cultural bias
Requires significant GPU computational resources for local deployment

Zapier

The free plan allows 100 tasks per month and only two-step Zaps, one trigger and one action
Multi-step Zaps, filters, paths, webhooks and the formatter all require a paid plan
Premium app connectors are withheld from the free plan
Free Zaps poll for new data every 15 minutes against 2 minutes on Professional and 1 minute on Team
Paying monthly rather than annually costs 50 percent more, so the 2,000-task Professional plan is $73.50 a month instead of $49
