According to Meteor official documentation −
Web and Mobile − Meteor offers a platform for developing Web, Android and IOS apps.
Universal Apps − The same code for web browsers and mobile devices.
Packages − Huge number of packages that are easy to install and use.
Meteor Galaxy − Cloud service for Meteor app deployment.
Meteor isn't very suitable for large and complex applications.
There is a lot of magic going on when working with Meteor, so developers might find themselves limited in some way.
