What is a plugin vs SaaS?

SaaS (Software as a Service) is like renting a tool from the internet that you use in your web browser โ€” think of it like Netflix for software [1]. A plugin is like an add-on or extension you can attach to that tool to make it do extra things, kind of like adding a special lens to a camera [2][3].

Why would you use a plugin?

Plugins let you customize your SaaS tool to do exactly what you need without having to buy a completely different program [3]. It's like having a basic toy and then adding special pieces to make it more fun.

How do plugins and SaaS work together?

When you use SaaS software, sometimes it comes with the ability to add plugins that connect to it and give it new superpowers [1][2]. You don't have to install anything on your computer โ€” everything happens online.

Are they the same thing?

No โ€” SaaS is the main tool you rent, and plugins are optional add-ons that make it better [1][3]. Think of SaaS like a smartphone and plugins like the apps you download for it.
