Now that Curseforge has revoked API access from third-party addon managers like WowUp and Ajour, are there currently any plans to host this addon elsewhere (Wago, WowInterface)? If not, would you be open to using BigWigs Packager to append formatted zips so that the aforementioned third-party addon clients can install directly from this repo?

BigWigs Packager Action

I second this :-) Would love to see this addon hosted anywhere else other than Curse xx

Wago would be best. There they are also supported and their work is paid!
And we can further update it with WowUp. Both sides won :)

Would love to see this anywhere other than curse as well. :)

I will try and host this somewhere else!

#57 adds support for CurseBreaker and any other add-on manager that can use GitHub releases.

I have been using wago.io for addon management - it puts everything in the one place with your weak aura updates

The maintained version of this addon has support for multiple addon managers: https://www.curseforge.com/wow/addons/pet-battle-scripts
