NythyCleaner is a Mac utility built solo by an independent developer in Strasbourg, France — no investors, no telemetry, no data leaving your Mac. Unlike CleanMyMac or similar tools, it's built specifically for developers: 22 Xcode categories, Docker & Homebrew management, CVE security audit across 8 package managers, exact SHA-256 duplicate finder, iCloud Drive treemap, and live Apple Silicon monitoring (CPU, GPU, Neural Engine). Free tier for analysis & monitoring.
