brreg-snap

One-click Brønnøysundregistrene lookups on Norwegian company sites — no content scripts, no trackers.

Click the toolbar icon on any Norwegian company site to surface data from Brønnøysundregistrene — managing director, board, signing rights, latest filed accounts — without the page knowing you're there. Three surfaces (popup, details, sidebar) share one thin data layer; smart lookup keys off URL or page title and falls back to a "did you mean …?" picker on ambiguity. The differentiator is what it doesn't do: no content_scripts, activeTab + storage only, single API host (data.brreg.no), zero third-party trackers. v1.0.0 shipped 2026-05-16; listed on Mozilla Add-ons.

Orkla.com homepage visible to the right of the sidebar with the headline 'A leading industrial investment company'. — sidebar docked on orkla.com — extension surface lives in-browser, never injected into the page
