 # What is Mafl?
+
+`Mafl` is a very flexible tool for creating your own homepage.
+It allows you to create lists of services, categorize and track the performance of certain services.
+
+Ideal for those who have their own home server with a bunch of services.
+With `Mafl` you can quickly and easily collect all links in one place.
+
+In addition to the functionality of regular lists, there are dynamic services. They connect to third-party APIs.
+They receive the necessary information and display it on the service card. All information is protected.
+API requests are hidden from the client in a separate application layer.
