MAMP
MAMP is a local web development app for macOS that lets you run Apache or Nginx, MySQL, and PHP on your Mac for testing sites offline.
What is MAMP?
MAMP is a macOS developer tool for building and testing websites on a local computer before publishing them online. It gives web developers a ready-to-use local server environment with Apache or Nginx, MySQL, and PHP in one app, so projects can run without configuring each component manually. Common uses include developing WordPress sites, testing PHP applications, managing local databases, and checking site behavior without uploading files to a live server. MAMP is aimed at developers, designers, students, and anyone who needs a self-contained web stack on Mac. It fits local development workflows where you want a quick way to start and stop services, switch environments, and work offline.
Key features
- Run a local Apache or Nginx web server on your Mac
- Use bundled MySQL and PHP for website development and testing
- Develop and preview WordPress, CMS, and PHP projects offline
- Start and stop local server services from one app
- Manage local web project folders for testing in a browser

Safety overview
Status: Safe
MAMP is legitimate local web development software. It runs local web and database services on your Mac, so network activity and background server processes are normal while you are using it. Because it can host local sites and databases, keep any test projects and database contents protected the same way you would protect other development files, especially if you enable broader network access. Remove it only if you no longer use its local server environment.
Recommendation: Keep MAMP if you use your Mac for web development, local CMS testing, or PHP and database work. If you no longer run local websites or development stacks, you can remove it along with its related support files to free space and avoid leaving unused server components installed.
