No Development Line Selected

I have an error when I want to open the Mendix studio on the internet and I cant get it to open. It says "No Development Line Selected" and I can only use studio pro and running it there doesn’t fix it.

You can enable Mendix Studio for you project in Studio Pro.

This paragraph (link) describes how to enable Studio on a specific branch / main line.



  • When you create a new App from the Mendix Portal (, using the ‘Create App’ flow, Mendix Studio is by default enabled on the main line. This to provide a smooth online flow from ‘Create app’ to ‘Edit App’ in Mendix Studio.
  • When you create an app in Studio Pro, the Mendix Studio is not yet enabled on a development line (main line or branch). The development team using Studio Pro can enable Studio when team members want to use Studio.
