Fritzing has quite a few electronic parts built-in and there are third-party libraries, but sometimes, your circuit might be using some new or rare component that isn’t included in any of them.
The main advantage Fritzing has over other free circuit design tools like Eagle or KiCAD EDA is the ability to create the circuits in “breadboard” view – basically just like using real wires to connect real components on a real workbench. Fritzing is an open-source prototyping platform that allows its users to easily create electrical circuits.
