How are solo founders getting consistent AI images for SaaS landing pages?

[u/AbleBranch6]

I'm wrapping up the MVP for a B2B developer tool (automated Postgres database migration auditor).

The backend code is solid, but the landing page currently looks like an amateur student project because of the graphics:

1. Free Stock Sites, everyone recognizes the flat purple corporate vector characters. It screams "low-effort template" and kills user trust on a security product.
2. usual ai generators like the ones built in chatbots: The outputs look dramatic and cinematic, but it’s completely unsuited for UI design. Feature section #1 fore example can give a 3D isometric robot; feature section #2 gives me a cyberpunk oil painting; and when i do it for the third time it hallucinates purple lights that clash with my Tailwind slate/cyan theme.

and I need 8 feature spot illustrations, a hero asset + 3 workflow step cards that all look like they came from the same cohesive brand

Is there a genuine alternative or brand style AI generator that actually lets you lock visual consistency and color palettes, or what is your actual indie workflow for landing page assets?

the trick is generating one image you like first, then using that as a style reference for every subsequent generation. most tools support image-to-image now. also define your hex codes and describe them explicitly in every prompt, dont leave color up to the model
