So I don't want to be rude, and am saying this purely as feedback since you asked and I detect a bit frustation - the wealthfolio site linked in the post presents a lot better than your one linked in your github.

Nominally they appear to be very similar like you say (open source, locally hosted etc), but the presentation does make a big difference for at-a-glance engagement. The wealthfolio is just... very pleasant to look at. The site largely focuses on what the value to the reader is, versus 'how do I get it running'.

Just my thoughts. I know it's incredibly frustrating when you see a copy/version of something you've made, but it gets more attention. But honestly could also just be the mood of the day. There may just be nothing to read into here.

+1, very polite way of saying it. of course there's a difference between the two posts. open source is interesting but not enough with a financial app, since it's all about trust + usefulness.

landing page needs to look good and communicate the value prop super effectively. If it doesn't look good you'll lose people's interest in about 2 seconds.
