Hi BattySeahorse19 !
We have made a comparison, https://clear.ml/blog/stacking-up-against-the-competition/ but as this industry moves in lightning-speed, this is probably already outdated 🙂
I am not closely following MLFLow so some of the features I'll discuss below might be outdated but the gist of it is this:
ClearML has an orchestration part, data management, serving, pipelines, Hyperparameter optimziation while MLFlow doesn't. ClearML offers a hosted Saas while MLFlow needs to be served by yourself. IIRC, ClearML supports more graphs types and has more features around downloading them, better comparing information and so on.
These are I think the big ticket items, there are more, and each tool gives a little different feeling when using it.
