Auth0 vs Satellizer: What are the differences?
Developers describe Auth0 as "Token-based Single Sign On for your Apps and APIs with social, databases and enterprise identities". A set of unified APIs and tools that instantly enables Single Sign On and user management to all your applications. On the other hand, Satellizer is detailed as "Token-based AngularJS Authentication". Satellizer is a simple to use, end-to-end, token-based authentication module for AngularJS with built-in support for Google, Facebook, LinkedIn, Twitter authentication providers, plus Email and Password sign-in method. You are not limited to the sign-in options above, in fact you can add any OAuth 1.0 or OAuth 2.0 provider by passing provider-specific information during the configuration step.
Auth0 and Satellizer belong to "User Management and Authentication" category of the tech stack.
"JSON web token" is the primary reason why developers consider Auth0 over the competitors, whereas "Oauth with angular is a pain in the ass" was stated as the key factor in picking Satellizer.
