Updating is as simple as clicking a button, with a separate section for searching the CurseForge repository to download other addons.
Once actually installed, the app is very straightforward and works much like you'd expect - updating addons without Overwolf's overlay or other frills. Ignore the 'recommendation' and download the standalone version if you only want to manage addons without all the extra Overwolf functionality. Currently in Alpha, this client only supports Windows and World of Warcraft addons. In order to get the standalone version, you'll want to scroll down to CurseForge download options and select CurseForge Standalone (Alpha) from the drop down menu instead - or use this direct download link. Getting to the standalone app is a little misleading however, as the link in the article directs to the main download page for the Overwolf app.
We’ve taken this into consideration and developed a standalone version of the CurseForge app on Windows, based on Electron, which you can download here. Many of the community members voiced their preference for a leaner approach to managing mods.
