Try out rr first. It has at least half the magical unicorn sparkles you're looking for, is open source, and runs locally. It's not hard to modify. (I've done it, though not for any core functionality changes.) Then you'll be in a far better position to evaluate the additional benefits Pernosco might provide you. I think your reasons for being leery of it are valid, but there are very legitimate scenarios where it makes sense IMO. (Recording CI jobs automatically, collaborative debugging, situations where the critical dataflow is hard to follow...) And they integrate, too - you can upload rr recordings to Pernosco when you need the extra functionality. I guess it also depends on the pricing model, which I know nothing about.
