Hi Product Hunt! I'm Animesh, and I built OpenClean. Paid Mac cleaners are closed, mostly subscription-based, and you can't see what they actually delete. I wanted one I could read and trust. What's different: - Every cleaning rule is a readable YAML file, and the app shows why each item is safe to remove - Anything that isn't trivially regenerable goes to a quarantine first, with History and Restore for 1-90 days - The Uninstaller moves an app and its leftovers together, so an uninstall can be undone too - No accounts, no analytics; the only network call is a daily update check you can turn off - A CLI with JSON output, plus cleanup for Xcode, npm, Cargo, Gradle, Ollama and Hugging Face caches It's free, GPL-3.0, native Swift, and signed and notarized. I'd love your feedback: what did it find on your Mac, what felt unclear, and which rules should I add? Issues and rule-pack PRs are very welcome.
