Activity Monitor X records what each process on your Mac does and keeps the history, so you can see what made your Mac slow, and when.
Needs macOS 26 and Apple silicon. Free and open source under the MIT license.
Every process, all the time
A helper records CPU, memory, disk, energy, network and GPU for each process, also while the app is closed.
History by app
One chart and one table show which apps used your Mac, from the last 5 minutes to 90 days.
