Would you consider hosting your add-ons here so those of us who wish may avoid Overwolf? Thank you!

This one and MoveAnything are at the top of my list!

Here's the conversation on another add-on:
SLOKnightfall/BetterWardrobe#250

Yep. Just adding a release zip to your Release assets would be a good step. This and adding some tags (like wow-addon, addon, world-of-warcraft) would – probably – make it eligible for the Github catalogue of instawow or/and strongbox.

Ideally you could register the repo with WoWUp Hub. This requires a release zip and a release.json, and AFAIK you still need to register each addon individually on their Discord channel. --> Yes, still required, just verified with a new addon of my own, and asked “why not using a catalogue?” – the answer was “currently for economy reasons”.

Just posting the addon on Wago Addons would also be a good thing. The process is really simple, it can grab your release from Github, also the ReadMe etc. The BigWigsPackager can save you some work too.

so those of us who wish may avoid Overwolf?

I don’t think anyone in their right mind uses this Overwolf stuff ;)
