uOptimise vs CCleaner: an honest comparison
CCleaner is the name most people know in this category, and it has been around for two decades. Well known and right for you are not the same thing, though. Here is a straight comparison with no spin, including the cases where CCleaner is still the better pick.
Updated 2026-07-02. CCleaner details reflect public information at the time of writing; their current pricing and features are on their own site.
The quick verdict
Choose CCleaner if you want a free tool or need macOS and Android support. Choose uOptimise if you want one clean Windows app with no ads, no subscription and no bundled offers, that shows you every change before making it and takes a System Restore point first, for $4.99 once.
Side by side
| uOptimise | CCleaner | |
|---|---|---|
| Price | $4.99 once, yours for life | Free tier; CCleaner Professional is a yearly subscription (current pricing on their site) |
| Ads and upgrade prompts | None, ever | The free version includes in-app upgrade offers |
| Bundled offers in the installer | Never | Installers have historically offered optional bundled software |
| Trying it | The full app, free for 48 hours, no card | Free tier with reduced features |
| Before changes are made | A System Restore point, automatically, every time | Prompts to back up the registry before registry cleaning |
| Download verification | SHA-256 checksum published for every release | See their site |
| Platforms | Windows 10 and 11 | Windows, macOS and Android |
Pricing: once vs yearly
uOptimise costs $4.99, paid one time. Every feature is included, there is no locked pro tier, and there is nothing to renew or cancel. CCleaner offers a feature-limited free version, and its Professional tier is sold as a yearly subscription. Over a few years the maths diverges quickly, and subscriptions in this category have a habit of auto-renewing quietly.
We keep the price low on purpose: many people paying a little once, rather than fewer people paying every year. That is the entire business model, which is why the app has no ads and nothing bundled.
Safety and reversibility
The biggest risk with any optimiser is a change you cannot undo. uOptimise creates a System Restore point before every change, shows you the full plan before anything runs, and journals what it touched. CCleaner prompts you to back up the registry before registry cleaning, which is good, but the restore-first habit is not applied to everything it does.
uOptimise also sticks to documented Windows APIs and never injects into other programs, so changes keep working across Windows updates. You can read more on our security page.
Where CCleaner is a fine choice
If you want a free tool for occasional junk cleaning, need macOS or Android versions, or already trust its workflow, CCleaner does that job and has for years. We would rather tell you that plainly than pretend otherwise. Its 2017 supply-chain incident was serious and widely reported, but it was also nine years ago and the product has moved on.
Where uOptimise fits better
uOptimise is built for people who are done with the free-tool trade:
One clean app: optimise, monitor, repair, storage and privacy in a single console
No ads, no upgrade nags, no bundled offers, no subscription
Every change listed before it runs, restore point taken first
SHA-256 checksum published for every release so you can verify your download
The honest caveat
uOptimise is a newer app from a small publisher and is not yet code-signed, so Windows SmartScreen may warn on first install. That is normal for a new publisher, not a verdict on the software. You can verify any download against the SHA-256 checksum we publish for every release on the download page.
