Amazon Cognito vs Satellizer: What are the differences?
What is Amazon Cognito? Securely manage and synchronize app data for your users across their mobile devices. You can create unique identities for your users through a number of public login providers (Amazon, Facebook, and Google) and also support unauthenticated guests. You can save app data locally on users’ devices allowing your applications to work even when the devices are offline.
What is Satellizer? 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.
Amazon Cognito and Satellizer can be categorized as "User Management and Authentication" tools.
"Backed by Amazon" is the primary reason why developers consider Amazon Cognito over the competitors, whereas "Oauth with angular is a pain in the ass" was stated as the key factor in picking Satellizer.
Satellizer is an open source tool with 8.08K GitHub stars and 1.27K GitHub forks. Here's a link to Satellizer's open source repository on GitHub.
I started our team on Amazon Cognito because I was a Solutions Architect at AWS and found it really easy to follow the tutorials and get a basic app up and running with it.
When our team started working with it, they very quickly became frustrated because of the poor documentation. After 4 days of trying to get all the basic passwordless auth working, our lead engineer made the decision to abandon it and try Auth0... and managed to get everything implemented in 4 hours.
The consensus was that Cognito just isn't mature enough or well-documented, and that the implementation does not cater for real world use cases the way that it should. I believe Amplify has made some of this simpler, but I would still recommend Auth0 as it's been bulletproof for us, and is a sensible price.
