Niagara was an easy 5 stars and lifetime purchase, but I now have a seething hatred for apps that stick random words as a prefix; for example, “myCigna” or “Fly Delta” because it ruins alphabetical sorting. I rate them 1 star for their ridiculous naming practices, but I feel like I need to do something more drastic to communicate my anger.

You might like ERPNext, Akaunting, or odoo as mentioned by another user

I haven’t looked into specific apps, but I have been wanting to try various trained models and figured just self hosting jupyterhub and getting models from hugging face would be a quick and flexible way to do it

Mainly just less to install when I inevitably wipe my PC again

It sounds like you may like NixOS if you haven’t tried it
