The CDC's Wastewater Surveillance dashboard can answer simple questions like whether whether line go up nationally or in specific counties, but some graphs don't have direct replacements. The year-over-year dashboard could not predict future spikes, but it was helpful predicting rate of decline:
That one can be remade using existing data, though it lacks variant data.
The one that I paid more attention to was the COVID-19 Variant Trends over Time chart, which illustrates transmission advantage of different variants by how quickly they become dominant:
CoVariants.org maybe has a comparable chart (It doesn't show KP.2 yet, but neither did Biobot). Unlike Biobot, they have variant charts for other countries and individual US states.
The CDC's 2-week variant chart does include KP.2/KP.3, but because it doesn't group sublineages like Biobot did, it might not not be as coherent over a larger period than 2 weeks.
