I recently published v0.6.7 (release notes: https://github.com/fsmv/daemon/releases/tag/v0.6.7)
I'm always surprised at how many little features a reverse proxy server needs to support any kind of web technology. Glad to have gotten this done because I wasn't sure how I wanted to implement the multiple http path pattern registrations for the same port for a long time and I finally figured it out by trying both options and deciding i didn't like one of them more.
Now I'm working on automatic lets encrypt certs and I'm very excited about it. It's going to be almost no configuration just go install ask.systems/daemon and you can have a website with full encryption support (and run things in minimal chroot containers) for multiple backend servers.
