Supertokens

Offers open source user authentication

SuperTokens enables developers to quickly implement user authentication without giving up control.

Our frontend SDK consists of prebuilt UI is hosted natively on your website - enabling you to easily control the end user experience (as opposed to a UI hosted by a 3rd party authentication provider). Similarly, all the auth logic resides on the SuperTokens backend SDK that integrates within your API layer (Node, GoLang Python) as opposed to the logic being hosted by a 3rd party provider where you have limited control.
