Production Designed Provider around Nano Banana?

Hey! I look for a provider that is actually made for production.
Meaning: separate ref uploads for products and scenes, tags to organize creations, specific prompt fields for product details, and a clean gallery to manage everything.

Higgsfield, Fal dot ai, Freepik and similar tools are not built for this. They are made for random one off creations. Also higgsfield and co feel like scams most of the times. Slower and weird sometimes.
What do studios or real productions use for consistent workflows

I also thought about building something inside Google AI Studio, but not sure if that makes sense long term.

Any ideas or tips are welcome. Thanks a lot!
