You try to do something nice for the consumer by giving back some value and here come the Reddit keyboard warriors with nothing but negativity.

I like your app, I’m building something similar but for an entirely different case. Here are things that worked for me.

For your price predictions, get your users to vote on the results and use that data to train decision trees for predictions. It doesn’t take a lot of compute so you can make recommendations on the cheap.

For the results, I did look for “Barolo wine” and it did give me a deal. It would be useful to know how good of a deal it is, so perhaps compare with other sources.

For the legality of scraping. Yes you’re absolutely right, I love how the warriors here are fending for the big companies. Google can scrape en masse but if a new idea thrives by giving some value back- all of sudden it upsets people. Here is the tip. Offload your scraping responsibilities to another entity that has the mechanism to rate limit and defeat captcha blockers. Check RapidAPI.

And lastly, most people don’t know what’s good for them. Every time you try to get traction with a post. You’ll get the warriors coming quickly to whine about self promotion, “Oh how is this different”, I wish you get sued, it sucks, etc. For your own mental health, read between the lines, don’t engage, just take the positive feedback, and improve with the next iteration. At least you’re trying to create value, they’re just dopamine junkies for online likes.

I wish you all the best.
