Site: https://www.compareempire.com/us (US), https://www.compareempire.com/uk (UK), root is Australia

What it is: a price comparison site for electronics. A GitHub Action scrapes 26 US, 22 UK and 30+ Australian stores every morning, matches the same product across stores, writes JSON into the repo, and Vercel rebuilds about 28,800 static pages from it.

Bits that might interest you:

Matching is the hard part. Model codes and part numbers first, then a strict bag of words with per category noise lists. A wrong merge is worse than a missed one, so it refuses rather than guesses.

Regions without breaking URLs: Australia stays at the root and the US and UK live under /us and /uk, all from the same views with a region argument. Product objects carry their region, so links, currency and price checks follow automatically.

Cost: everything is static, so it runs on the CDN.…
