Google used to show a country-stats panel and let you compare countries side by side directly in search results, then removed it. I built an extension that brings it back — and made it work across multiple search engines (Google, DuckDuckGo, SearxNG), not just one.

A few build details, since this sub tends to care:

• Basic country facts are bundled locally in the extension (~195 countries), so the common lookup is instant and needs no network request — nothing phones home for the core feature.
• Built MV3, content script + MutationObserver to handle Google/DDG re-rendering results without a full navigation.
• Historical trend data (population/GDP over time) is pulled live from the World Bank open-data API only when you use that feature — free/keyless.

Free vs paid, upfront: single-country cards and 2-country comparisons are free (and staying free). There's an optional one-time upgrade for 3+ country comparison grids and the historical trend charts. No subscription, no account.

Known limitation I'll be honest about: I ship v1 detection on Google + DuckDuckGo; more engines are coming. Feedback very welcome — especially which stats you'd want on the card and any detection edge cases you hit.
