I saw lots of Disk Space Cleaner with > $10 price, which are basically a good interface for your Mac native storage. I built SpareDisk over the last few days, kept it bare minimum in terms of bloat features but focused on speed, parallelism, and queue management.

You can review your whole file system without hanging the computer. This is version 1. I have tested it well over multiple laptops.

The code is open source, and if you can compile it: use it for free, you can customize your design and stuff.

If you want to get an Apple notarized app ready to use using the source code, you can download it from the website for "pay whatever you want" (minimum $2).
