# Nadhif: clean your Mac with developer tools and protect your website and server from hackers > Nadhif is the Mac app our team is building at Alhamou. It cleans your Mac and explains every file before it touches it, gives developers tools for the gigabytes Xcode, Node and Docker leave behind, and tests your websites and servers for vulnerabilities, so you can close them before anyone uses them. - Author: [Emad Alhamou](https://hamou.de/), Founder & Product Builder - Published: 2026-11-07 (updated 2026-11-07) - Language: English - Web page: https://hamou.de/articles/nadhif/ - Other languages: [Deutsch](https://hamou.de/de/articles/nadhif/index.md), [العربية](https://hamou.de/ar/articles/nadhif/index.md) - Video: [Nadhif — Mac cleaner, developer tools and security checks (animated overview)](https://www.youtube.com/watch?v=nDOR34xE_fQ) - Product: [Nadhif](https://nadhif.hamou.de/) · In development · macOS 15 or later · Apple silicon ## What is Nadhif? Nadhif (Arabic for “clean”) is a native macOS app for Macs with Apple silicon running macOS 15 or later. It does three jobs in one quiet window: it cleans your Mac without risk, it clears the space your developer tools quietly fill, and it finds the weak spots in your Mac, your servers and your websites before hackers do. Our team at Alhamou has been building Nadhif since September 2026, and it is still in active development. The app speaks English, German and Arabic. ## Clean your Mac without the fear Most cleaners ask you to trust one big button. Nadhif works the other way round. A single scan finds caches, logs, developer leftovers, old installers and large files, and every category comes with one line that explains what it is and why removing it is safe, or why it is not. You decide what goes. Cleaning is a move, not a delete. Everything Nadhif cleans goes to **Recently Cleaned**, where you can restore it for seven days. Your personal files and your keys are off limits. The uninstaller removes an app together with its files in Library, and finds what is left of apps you deleted before. ## Tools for developers A developer's Mac fills up in places most cleaners never look. Nadhif knows them: Xcode data, simulators, `node_modules` folders, Homebrew and Docker, the places that quietly eat gigabytes on a developer's Mac. ## Protect your website and server from hackers The third part of Nadhif looks for the gaps attackers get in through: - **This Mac:** a security check of the Mac you are working on. - **Servers:** scans Debian and Ubuntu servers for vulnerabilities over SSH. - **Websites:** tests the websites you own with real attack techniques, so you find weak spots before someone else does. ## Private by design Nadhif collects no personal data and leaves no process running in the background. Scan results and security reports stay on your Mac. ## Who is behind Nadhif We are a team of developers at Alhamou, and we build Nadhif together. We follow the same rule in everything we make: good technology does not show off its complexity, it makes people's lives simpler. ## Frequently asked questions ### Is Nadhif safe to use? Yes.
