F-Droid is a community-maintained software repository for Android, similar to the Google Play store. The main repository, hosted by the project, contains only free and open source apps. Applications can be browsed, downloaded and installed from the F-Droid website or client app without the need to register for an account. "Anti-Features" such as advertising, user tracking, or dependence on nonfree software are flagged in app descriptions. The website also offers the source code of applications it hosts.
