Browser extension
Overlay competitor prices on Steam, Epic, and GOG product pages. Buy buttons route through tracked /go/?from=extension so operators can measure the channel — ranking stays best-price first, never commission-biased.
Install (sideload)
- Build from the repo:
pnpm --filter @cheapgamesfinder/browser-extension build - Chrome: open
chrome://extensions, enable Developer mode, Load unpacked →apps/browser-extension/dist - Firefox: open
about:debugging#/runtime/this-firefox, Load Temporary Add-on →dist/manifest.json
Chrome Web Store / Firefox AMO
The package is Manifest V3 with icons, homepage, and privacy URL ready for store review. Operators submit the zip from npm run build:zip — publishing still needs a human developer account (we do not invent store credentials).
