# URLCheck (open-source utility app)

> URLCheck is a free, open-source utility app for Android. Allows analyzing (or sharing) URLs before opening them. It has 2,089 GitHub stars and is released under the CC-BY-4.0 license, and you can install it from F-Droid and Google Play.

This application acts as an intermediary when opening url links. When you do so, a window containing information about the url is displayed, allowing you to make changes to it as well. Specially useful when you need to open an external link either from an email, a social network app or others. URLCheck is developed by TrianguloY, originally for personal use. It is open source (under CC BY 4.0 license), free, without any ads or trackers, light sized and using as few permissions as necessary (only the internet permission, for module checks that will only be performed when the user request them).
