Competitive intelligence
Competitor intelligence for Shopify, as a browser extension.
TypeScript · Chrome MV3 · Supabase
- The problem
- Store owners checked competitors by hand, tab by tab, and lost the history the moment they closed the browser.
- Constraints
- Manifest V3 removed persistent background pages. Everything had to survive a service worker that stops without warning.
- What was built
- An extension that reads a competitor page, extracts pricing and catalogue changes, and keeps a history that outlives the tab.
- What happened after
- In development, with the data model already in production.
