I know this is super off-topic but I’ve needed to design this web experience myself over the past few years (and ended up making visitors use Google Sheets with filters they adjust).

It seems you've got some property/binary/numeric filters already in there and if you could load the data from a js/json file, this UI could be entirely open source and customizable. I’d just fork and put my own data, set my own sliders and good to go.

Just a thought if you ever wanted to open source it. It would be a superb experience for many developers.
