Damn, how did I miss this? Looks like a really nice "self-hosted nYNAB". Only downside is that the native apps are unmaintained since the project went open-source, and the web UI isn't responsive (yet) - but looks like there are decent efforts to make the web UI into a usable PWA, if those succeed this may be my move away from nYNAB.
We've been working on getting the electron app up and running, you can download beta builds of it already, and I think it's mostly there.
Yep - There is on-going work to get good mobile support on the web app too!
Oh wow, this does look REALLY good, at least the demo does! Going to give it a spin.
