Setting up dev environment

Building apps requires the Overwolf client, you can view the changelog here and find out what's new. This includes new in-game events functionality you can use in your app.

Note that developers don't have to work with the Developers version of the client, but it usually has new features and functions still in testing that might be useful.


To develop, load or run unpacked or unreleased apps, you have to get whitelisted first.

Developers Version

  • Download the Overwolf Developers Client.
  • If you already installed the OW client public version, you can easily switch it to the developers channel/version:
    • Open Overwolf setting.
    • Go to about.
    • Press Ctrl + Shift + Left mouse client on the Overwolf logo.
    • Write in the channel: Developers.
    • Update and Relaunch.
