The official website of the Swedish government.
Sweden is in Europe. This page collects 4 websites and apps that are actually used there, grouped into 4 categories. Every entry links to the official site and carries a short description, so you can tell at a glance what each platform is for before you click through.
The most populated categories are Online Shopping, News & Media, Government & Public Services, Payments & Finance. Browsing by category is usually faster than scanning the whole list: if you are looking for a local marketplace, a ride-hailing app or a news portal, the category page for Sweden narrows the list down immediately.
Among the better-known entries are Aftonbladet, Blocket, Swish, Regeringen.se. These are mainstream services rather than niche ones, which makes them a reasonable starting point if you are trying to understand how the internet in Sweden is organised.
