Country Filter for X (Twitter)

Live

A browser extension that hides X (Twitter) posts from countries you pick, detecting location locally with no external servers or sign-up. A niche personal timeline filter, not a developer tool.

No sign-upWorks offlineOpen sourceNo tracking
What to know▼
How it works
A browser extension where you check countries in a popup and posts from those countries disappear from your X For You feed, Following feed, search, and reply threads; detection runs locally using known accounts, country/city keywords, post language, and public profile location.
What's different
No sign-up, no tracking, and no external servers — settings and detection stay in your browser; open source (MIT).
Best for
X users who want to filter their timeline by country without sending data to a third-party server.
