OpenClean
Free, open-source Windows cleaner with zero telemetry
OpenClean shows an honest picture of your Windows PC and cleans only what you choose. No fake speed boosts, no invented problems, no account, no background service, and no telemetry. Every number is a real measurement. Free & open source.
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. 🙌
