Hazel solves a different problem than DaisyDisk: preventing storage chaos instead of diagnosing it after the fact. It watches folders and runs rules to automatically rename, move, tag, archive, or trash files, which reduces the need for periodic “where did my space go?” investigations.
If recurring clutter is the culprit—Downloads piling up, installers lingering, screenshots exploding—Hazel can enforce policies continuously. That makes it a better alternative when the goal is ongoing hygiene rather than occasional deep cleanups.
The real power comes from building deterministic “if this, then that” workflows that match how someone works. With scripting and automation hooks, Hazel can fit into sophisticated setups where a disk visualizer would only show the symptoms.
The trade-off is setup time: rules need to be created and refined, and it’s less useful for one-off emergency space recovery. For people who want automation that quietly keeps a Mac tidy, Hazel is the more scalable choice than DaisyDisk.
