Hey Product Hunt 👋 I'm the maker of OpenClean. I built it because every "PC cleaner" I tried did the same three things: invented problems, promised fake speed boosts, and buried an upsell in a scary red screen. So I made the opposite. OpenClean shows you an *honest* picture of your Windows system and cleans only what you choose: 🧭 Overview — a real system score with the exact factors behind it (reclaimable space, startup load, drive pressure), not a made-up number. 🧹 Cleanup — always preview temp files & caches before anything is deleted. You decide what goes. Never silent deletion. ⭐ Startup — see autostart entries and their real boot-time impact, and toggle them (never delete — always reversible). 🛡️ Privacy — find and clear privacy traces. 🗑️ Uninstall — programs by size + a scan for leftover folders/registry remnants. Single uninstall is always free. 📑 Duplicate finder — exact duplicates by SHA-256, safely removed. What OpenClean deliberately does NOT do: • No registry "cleaner" (it does more harm than good — we left it out on purpose) • No telemetry, no account, no background service • A free install makes zero network connections. None. It's open source (.NET 10 / WPF), code-signed, ships in 7 languages, and there's a portable single-file build that runs from a USB stick with no install and no .NET required. It's open-core: everything above is free forever. Two power-user conveniences (scheduled cleaning + batch uninstall) are an optional one-time purchase of €12.99 — no subscription — but the app never deletes programs itself, it always calls the vendor's own uninstaller. I'd genuinely love your feedback — especially on the "honesty" angle. Ask me anything, I'll be here all day. 🙌
