Yes: http://www.shadowstats.com/alternate_data/inflation-charts

However, I'm just answering your question, not endorsing that per se. Here's some skepticism, which I am also not endorsing, just balancing and emphasizing my lack of endorsement: https://munknee.com/debunking-validity-shadowstats-inflation...

Personally I suspect the answer is somewhere in between. Arguably it's not even a well-defined question. Clearly something like inflation and deflation can exist, even across large time periods, but there may be no single number that can ever capture it accurately. I am somewhat reminded of the difficulties of trying to fix an absolute reference frame in physics, especially when trying to fix it to locations on Earth over large periods of time.

Thanks for the links! Agreed, it’s extremely hard to do well - the basket of goods that one would consider reasonable doesn’t even stay the same over time, computers get added, gasoline (hopefully) drops out.
