The repo authgear-server includes the following components of Authgear:

• Authgear server (the core service)
• Portal (a web-interface for managing configurations in Authgear projects)
• AuthUI (a customizable User Interface (UI) for login, user registration, and profile settings pages)
• Admin API (provides a GraphQL interface for developers to interact with services and data on Authgear)

This repo is the open-source project that powers Authgear's authentication-as-a-service solution. It includes the code for the server, AuthUI, the Portal, and Admin API. You can use it to set up your own self-hosted instance of Authgear service.

These SDKs exist as standalone projects under the following repositories:

• JavaScript (Web) - NextJS, Vue, React, Angular
