Where does the "Localhost" come from? Did you enter this somewhere? trying to post from my Mastodon instance to my Lemmy instance How are you doing/triggering this?
The reason for the creation of AGPL is not "limiting" commercial use. It's there, so that a company commercially using your AGPL project is also required to publish its changes under AGPL, even if the only way they "distribute" the software is as a Application Service Procider (SaaS company). Because under regular GPL, this case wasn't covered, so big companies could use your code, modify it, offer it as a SaaS product and NOT publish their changes unter a free license.
AGPL specifically exists, so the rules around commercial SaaS use are clear – so I'd argue it's the opposite of "limiting commercial use".
HedgeDoc would be another contender
Yeah, it is. But I think they've dialled it down quite a bit. Or do you still have som examples where they claim to be open source? It's mostly users misunderstanding what OSS is.
