For web scraping, I recommend using a web scraping API, e.g. https://scrapingfish.com. This solves all potential problems with getting blocked and can make data extraction easier as well.

For the app, I've recently started using Remix (https://remix.run) and so far it seems to have been a good choice for me. There is a good integration with Remix in Mantine for front end: https://mantine.dev/guides/remix/. I think it's a good full stack choice if you just want to quickly build an app for your project/product.
