Epic's developer resources include a set of free services and tools which software developers can use to add network-based functionality to video games, and storefront distribution for video games.

There are three sets of resources:

• Epic Games Store (storefront distribution and games-store services)

• Epic Online Services (EOS)

• Kids Web Services (KWS)

The sets of resources have associated tools to configure and manage them with your game: the Epic Games Developer Portal (known as the "Developer Portal"), the KWS Developer Portal, SDKs and APIs.
