I tried it 3 months ago. It looked nice had some cool features, but It didn’t fit into my personal selfhosted Home server.
This is more or like to help less-tech savy people to secure their infrastructure, which is a good point, but can’t replace a complex wireguard, VPN, opnsense, 2FA , self-signed CA, docker installation.
It’s a bit like Nginx proxy manager, it’s good enough, does what it is suposed to do with minimal user inputs. Less prone to error, security issues…
As long as they continue to maintain the github repository and keep it free without any hidden ads/spyware or restrictions, I will continue to use their service.
