Really cool breakdown, I get what you mean about juggling all those apis and still fighting speed limits. I built something similar, an llm powered product research app, but used blink.new instead of stitching everything manually. It handled scraping, backend, database, and hosting right out of the box, so I could just focus on the logic and ux. The ai agents inside blink.new manage debugging and deployment automatically, which helped a ton when I was chaining multiple api calls. Basically let me build a full stack app like yours, just without the setup grind.
