AltFlag reveals the country of origin for any website you visit. Stay informed about who's behind the sites you use every day.
Your right to know. Your freedom to choose.
In today's interconnected world, we interact with countless websites daily—often without knowing where the companies behind them are based. AltFlag empowers you with transparency and choice.
Whether for political, ethical, economic, or personal reasons, everyone has the right to know the origin of the services they use. Some may want to:
AltFlag doesn't judge your choices—it simply gives you the information to make them.

How AltFlag identifies websites, sources its data, and finds alternatives
When you visit a website, AltFlag runs through a four-step lookup chain — entirely on your device — to find the company's country of origin.
We aggregate and cross-reference multiple trusted sources, then run automated verification pipelines weekly.
When a flagged site is detected, AltFlag suggests services from other countries in the same category.
