Infinitely Extensible
ExpressionEngine is a powerful and robust tool. But even the best tool has its limits. And when you reach those limits, ExpressionEngine’s add-on architecture lets you solve any problem in a fully-integrated way.
Developers love the ease with which they can solve unique problems with ExpressionEngine add-ons. ExpressionEngine allows them to create rich functionality that looks and feels native. And with a robust third-party developer library, there is no mountain too high, no valley too wide.
