LUNITE Download free

Need help?

Two ways to reach Lunite. No contact form, on purpose: it would add another outside service, and this site runs no scripts.

Two channels

In the app

SETTINGS > SEND A REPORT

Best when something in your check-up looks wrong: it sends your report card with your message. Click "See the exact card" to read everything first. The report isn't sent until you press SEND.

Questions

Is Lunite safe to run?

Lunite is signed, so Windows shows who published it (Luis Patino), and you can check the file's hash and signature before you run it. That proves you have the exact file Lunite published, not that it's safe, so here's what it does: the check-up only reads; fixes run only after you approve them on the FIX screen, and each keeps an undo (if a setting has changed since, or Lunite couldn't save its undo record, it tells you); the few things that can't be undone are marked before you agree. No software can promise it will never cause a problem, and Lunite comes as is, without a warranty (see the Terms).

Will it change anything without asking?

No. The check-up only reads; Lunite saves only its own files, like its results and report cards. Nothing changes without your yes: fixes run only from the FIX screen, removing a program or Windows' own disposable files has its own screen and its own consent, and the switches in SETTINGS change only when you flip them. Fixes for real problems start ticked and the rest start unticked; untick anything you don't want, and no fix runs until you press APPLY SELECTED FIXES. Each fix keeps its own undo; if a setting has changed since, or Lunite couldn't save its undo record, it tells you.

What leaves my PC?

Lunite sends none of your results or anything you type unless you press SEND. Your check-ups stay on your PC: no account, no telemetry, no analytics, no automatic crash reporting. Each check-up also makes a few network calls, such as name-server timing with Cloudflare and Google; they show your IP address to those servers and carry none of your results; winget, Microsoft's tool, may also send Microsoft its own usage data. Privacy sums them up, and ABOUT in the app lists every one.

Does it work on Windows 10?

Built and tested on Windows 11. Windows 10 works but is tested less: if anything looks off, send a report from Settings (Send a Report), or email luniteapp@gmail.com.

How do I remove it?

No installer, so no uninstaller. If you ever sent a report, write down your tag first. Then undo what you want in WHAT CHANGED, turn off the no-popup switch if you turned it on, press DELETE MY RECORDS in SETTINGS, close Lunite and delete Lunite.exe (and Lunite.previous.exe, if there is one), then delete %LOCALAPPDATA%\PCOptimizer (an early working name the folder still uses).

Is it really free?

Yes, today. Everything in this version is free, including the one-click fixes. A later version will charge once ($9.99 USD) for the app applying fixes for you. The check-up, scores, report and written steps stay free, so do UNDO and WHAT CHANGED, and any PC already using Lunite before then keeps the one-click fixes free. Pricing

Does it make my games faster?

Lunite doesn't promise a speed-up. It finds settings and hardware that are holding your PC back, tells you what it found and how sure it is, and lets you choose what to change. Results depend on your PC.

Why does my antivirus call it suspicious?

Lunite runs PowerShell scripts with no window and with -ExecutionPolicy Bypass, and security tools often flag that pattern. You can check the file's signature and hash and see where the scripts are written. If your security tool blocks Lunite, that's its call: check the file first, and if you're unsure, don't run it.

Is the code public?

No. Lunite isn't open source: its LICENSE keeps all rights, and its GitHub page hosts the downloads and documents, not the source. The PowerShell scripts it runs are ordinary text files written to a folder on your PC, so you can open them and read what they do; when Lunite runs as administrator, that folder opens only from an administrator window.

Something looks wrong in my report.

That's worth knowing. Use SETTINGS > SEND A REPORT (read the report before you send it), or email luniteapp@gmail.com.
