  Basket Buddy: compare quick-commerce prices without opening three apps

  Receiving the second-prize cheque at the SLAB Hackathon, CMR Institute of Technology

Inspiration

Comparing a grocery basket across quick-commerce apps means opening three apps and searching the same items three times.

What it does

Basket Buddy compares prices across quick-commerce sites. It writes what it learns about each site to a strategy file and reads it back on the next run, so every site gets easier after the first visit. It is read-only by design: no checkout, no payments.

How I built it

A browser agent on WebCMD with Node, using Claude for the reasoning, and a per-site strategy file as its memory.

Challenges I ran into

BigBasket blocked the agent. Instead of fighting it, Basket Buddy logs the block and moves on.
