I built a Chrome extension that lets you filter tweets by country.

  X recently added "Account based in [Country]" to profiles, so the location data is publicly available — X-Ray uses it
  to show location badges on every tweet and lets you blur or block tweets from selected countries.

  There's no native way to do this on X yet (though they're reportedly building one). So I built it.

  Tech: Chrome Extension (Manifest V3), Node.js backend, PostgreSQL. The extension intercepts X's GraphQL API responses
  to extract location data, caches it to avoid rate limits.

  It's free, 170+ countries, 9 languages.

  Happy to answer technical questions.
