Hey Product Hunt, I'm AJ. Like every developer I know, my SSD fills up with DerivedData, iOS Simulators, and node_modules faster than I can remember to clean them. The options I had: - CleanMyMac — $40/year, closed source, constant marketing push. - rm -rf — fine until you nuke something you shouldn't. - DaisyDisk — beautiful, but a visualizer, not a cleaner. So I built FreeUp. Open source, scans my whole Mac in seconds, frees up gigabytes with one keystroke. A few things I cared about: Speed. It walks the filesystem with BSD's fts(3) and bulk metadata APIs instead of Foundation's enumerator, and fans large targets (Xcode DerivedData, iOS DeviceSupport, Simulators) into a TaskGroup per immediate child directory. Scanning 250k+ files takes about 5 seconds on an M1. Safety. Duplicate detection does a head + tail + size-salt SHA-256 before the full hash, so container formats with identical headers don't waste a full read. APFS clones are detected, so "I freed 2 GB" means you actually did. Time Machine snapshots are flagged because they can hold bytes hostage after deletion. One admin prompt. Root-owned system files (the /Library/Logs/DiagnosticReports stuff) need sudo. Most cleaners skip them or flood you with 600 password prompts. FreeUp batches them into a single do shell script with administrator privileges + xargs rm — one prompt, whole batch cleaned. Paths are whitelisted against known reclaimable roots before any privileged operation. Built on: Swift 6 strict concurrency, SwiftUI, Inter + SF Mono, keyboard-first (⌘R scan, ⏎ confirm, ⌘A select all). MIT licensed. No subscription. No telemetry. No nags. I'd love feedback on: - Category heuristics — which folders should I add? - The admin elevation model — does it feel safe enough? - Any UI nits (it's a one-person design effort) Roast it honestly — that's how it gets better.
