## What it is
Elgg is an open-source rapid development framework for building socially aware web applications, written in PHP with MySQL. It provides a modular OOP core with DI services, pluggable authentication, an entity-based data model, access control, groups, notifications, and a large community plugin repository.

## Use cases
- build a social networking site in php
- create an intranet or private community platform
- self-host a campus or organization social network
- build a web app where users log in and share content
- develop a collaborative platform with user groups
- prototype a social web application with plugins

## When to choose
- you need a self-hosted social network or community platform in PHP
- you want a framework with built-in users, groups, access control, and notifications
- you want to extend functionality via a mature plugin ecosystem

## When to avoid
- you need a modern JavaScript SPA or a non-PHP stack
- you want a lightweight microframework rather than an opinionated full-stack engine
- you need a hosted SaaS social platform rather than self-hosting
