The Wireguard iOS app has an “on-demand” toggle that automatically connects when certain conditions are met (on cellular, on wifi, exclude certain networks, etc)

Totally agree there, I’m only aware it exists because I didn’t want to go through the hassle of setting up/maintaining either.

I assume “minimal” refers more to the fact that it won’t have all Omnivore features rather than it being uncomplicated to set up

So the title of the blog post is incorrect? I didn’t look at it super closely so apologies if I’m incorrect

Not sure if you were aware, you can run a minimal selfhosted Omnivore setup. Not sure if it will meet your needs or not
