Safeline originates from China, which is an issue IMO. -

Chinese people who don't necessarily agree with their state sponsored pals.Depends who wrote it and why.

There are some very intriguing/ interesting Chinese hackers etc living in Chiang Mai in northern Thailand see e.g. https://4thgenerationcivilization.substack.com/p/towards-civilizational-ai-our-central

Safeline originates from China, which is an issue IMO.@RoundHouse1924 I often gravitate to this thought, but then remember that what @robi says is true.
Consider Seafile as an example of an app which seems trusted.The problem is knowing the reliability.
I guess we have to rely on peer review, no. of GitHub stars, and the valiant efforts of code reviewers.It might be academic, as I asked for an AI review of feasibility of packaging for Cloudron, and it was essentially negative, too complex and not enough info about building (they assume a docker-compose deployment based on their image which is not officially published).
Someone more technical than me needs also to consider the issue of running a reverse proxy (SafeLine) in front of Cloudron's reverse proxy, especially when Safeline if packaged for Cloudron would be on same VPS as Cloudron's reverse proxy. Confused ? I sure am.

@timconsidine nesting reverse proxies is OK.
It happens already with Cloudron's Nginx and webservers that front multiple app servers in our Apps.
