Kiwisdr maintains the software that is used on the web frontends of their SDRs, they just disabled the feature and (at the time) people couldn't use it anymore.
There are other ways to triangulate signals, but that means buying receivers and putting feet on the ground.
what does triangulate mean here? i'm guessing locate.
Yes. From two or more sites plot the intersection of strongest signal radiating pattern, and the centroid is the most likely location of the transmission assuming it's single sourced, and you can plot directionality of the RF. This is called triangulation because at sea you are recommended to get at least 3 points of reference which becomes a "cocked hat" (by visual analogy) to the location being plotted, distances and angles being computed by.. triangulation. The seaborne method is directly analogous to radio signal finding.
