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.

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.

Common questions

Is uOptimise a full CCleaner replacement?
For cleaning junk files, trimming startup apps and managing what runs in the background, yes, and uOptimise adds repair (SFC and DISM), live hardware monitoring and privacy controls in the same app. What it does not do is run on macOS or Android. If you need those platforms, CCleaner still makes sense.
Why pay when CCleaner has a free version?
Free utilities still have costs, so they earn money another way: upgrade prompts, data, or bundled offers. uOptimise charges $4.99 once and does none of those things. Which trade you prefer is up to you, but it is a trade either way.
Can I try uOptimise before switching?
Yes. The trial gives you the complete app for 48 hours with no card required, so you can compare both tools on your own PC before deciding anything.
Is it safe to switch?
You do not have to commit. The two apps can be installed side by side, and uOptimise takes a System Restore point before every change it makes, so anything can be rolled back.

Compare them on your own PC

The fairest test is your own machine. The uOptimise trial is the complete app, free for 48 hours, no card required. Keep whichever tool earns its place.
