Good call-out. The directory pulls the prominent language from each project’s repo, which is JavaScript for Mailcow.

I should update the dataset to grab any languages above a certain % threshold (25%?) to prevent instances like this where something might fall through the cracks.

I also maintain a language filter over at selfh.st/apps that can be used to identify PHP-heavy platforms:

https://selfh.st/apps/?language=PHP

Thanks for always posting it in my absence!
