localhost — Local Host Guide
Looking for your local machine? Click the link below.
Go to: http://localhost
localhost | localhost 80 | localhost 8080
localhost is a local server environment for testing and running server-side scripts on your own computer.
Or try:
http://localhost:80 | http://localhost:8080 | http://localhost:8888 | http://localhost:7080 | http://localhost:3000

localhost - http://localhost
In computer networking, http://localhost is a hostname that refers to the current device used to access it, via the loopback network interface.
If you are running a web browser on your computer, your computer is considered the localhost. When used on a single machine, you usually do not need to specify it explicitly.
http://localhost is commonly used for testing and development. After installing WAMP, LAMP, or MAMP, developers often type localhost in the browser to access their local site.

Modern Dev Environments & Tools
Docker, Vite, reverse proxies, backends, and databases on localhost.
Beyond classic XAMPP/WAMP bundles, most teams today use **Docker** for services, **Vite** for frontend dev servers, and dedicated runtimes for APIs and databases — all reachable on **localhost**.
Default ports you will see often: **5173** (Vite), **3000** (NestJS/Next.js), **8000** (Laravel/Django), **5432** (PostgreSQL), **6379** (Redis).
See our port reference and conflict guides if something fails to start.

Web Servers
A web server is software that uses HTTP (Hypertext Transfer Protocol) to respond to client requests and deliver web pages. It can also refer to the computer or device running that software.
Web servers present website content to the user's browser. Every site on the internet has a unique IP address. Apache is one of the most common web servers (open source, large market share); Microsoft IIS is another popular choice.
Most popular web servers:
- Apache HTTP Server
- NGINX
- Apache Tomcat
- Node.js
- Lighttpd
- Microsoft IIS
- Jetty
- Oracle iPlanet
- LiteSpeed
- Gunicorn
- Cherokee
- Tornado
- HTTP File Server
- Hiawatha
- Xitami

Web Server Stacks
These software bundles are used to run dynamic websites or servers.
In computing, a solution stack (or software stack) is a set of software subsystems or components needed to build a complete platform so applications can run without extra software.
A web stack is the collection of software used to build websites, typically including an operating system, programming language, database, and web server.
A classic example is the LAMP stack: Linux (OS), Apache (HTTP server), MySQL (database), and PHP (server-side language).

Modern Frontend Stacks
Run Node.js dev servers on localhost to preview SPAs, SSR, and full-stack apps.
Modern frontend development rarely relies on traditional LAMP/WAMP bundles alone. Developers run Node.js dev servers locally to preview single-page apps, SSR sites, or full-stack frameworks.
These stacks cover build tools (Vite), meta-frameworks (Next.js, Astro), routing (React Router), microfrontends, and more — all quick to start on localhost.
Default dev URLs are often **http://localhost:3000** or **http://localhost:5173**; see each framework's docs for details.
