Hey everyone,

I'm building a personal price-comparison app in react native where users can scan a barcode or search for a product, and the app compares the prices across multiple Dutch supermarkets (like Albert Heijn, Jumbo, Dirk, etc.).

My backend is built with Flask and hosted for free on Vercel. However, I'm running into the classic cloud-hosting wall: almost all major supermarket websites block or throw 403 forbidden errors on standard requests from Vercel's datacenter IPs due to anti-bot protection.

Since I want to keep this lightweight and free (serverless), I'm looking for architectural advice on how people usually build multi-supermarket scrapers or price checkers:

• What are the best free or low-cost ways to bypass these blocks for multiple different domains?
• Are there alternative public endpoints, unofficial APIs, or lightweight proxy setups that make it possible to aggregate prices from multiple grocery chains?

Any architectural tips, code patterns, or alternative approaches would be super helpful!

I’m making a rocket in Build A Boat. I want the Glue Block to disappear and the Jet Turbine to turn on from the same F press.

Currently, the first press removes the Glue Block, and I need to press F again for the turbine to activate.

Any ideas?

Meaby with a Delay Block?
