DeepClean - Mac cleaner that digs deeper: Find the hidden files eating 50+ GB of your Mac's storage

I kept running out of storage on my MacBook and couldn't figure out where it was all going. The "Manage Storage" screen in macOS was useless. It just showed vague categories like "Other" taking up 80 GB. I'd spend an hour digging through ~/Library, manually deleting Xcode build files, old Docker images, npm caches from projects I hadn't touched in months. And every time I felt like I was missing stuff. Because I was. I tried CleanMyMac and a couple of other tools. They cleared browser caches and system logs, which helped a little, but they completely ignored developer stuff. No idea what DerivedData was. No idea about Gradle caches or pip virtual environments or stale node_modules folders. So I started building something for myself. Just a simple scanner at first that would check the 5 or 6 directories I always forgot about. Then it grew. I added duplicate file detection because I had the same photos scattered across three folders. But I didn't want to just compare filenames, that misses too much. So I built a three-phase hash system that checks actual file contents. That caught way more than I expected. The biggest shift in my approach was adding confidence ratings. Early on I accidentally deleted something I shouldn't have and it freaked me out. After that I built a classification system where every single item gets rated Safe, Review, or Caution based on what the file actually is, not just its extension. That changed the whole experience. I stopped being nervous about cleaning up. The app runs 100% on your Mac. Nothing gets sent anywhere. And it's a one time purchase because I personally hate subscriptions for utility software. First scan usually finds 30-50 GB of stuff people had no idea was there. That moment when someone sees the number for the first time is pretty satisfying. Would love to hear what you think, and if there are tools or caches I should add support for.
