OAuth.io vs OmniAuth: What are the differences?

What is OAuth.io? OAuth That Just Works. OAuth is a protocol that aimed to provide a single secure recipe to manage authorizations. It is now used by almost every web application. However, 30+ different implementations coexist. OAuth.io fixes this massive problem by acting as a universal adapter, thanks to a robust API. With OAuth.io integrating OAuth takes minutes instead of hours or days.

What is OmniAuth? OmniAuth is a flexible authentication system utilizing Rack middleware. OmniAuth is a Ruby authentication framework aimed to abstract away the difficulties of working with various types of authentication providers. It is meant to be hooked up to just about any system, from social networks to enterprise systems to simple username and password authentication.

OAuth.io and OmniAuth can be primarily classified as "User Management and Authentication" tools.

Some of the features offered by OAuth.io are:

• Quickly integrate API providers
• More than 100 providers available
• Secured encrypted API

On the other hand, OmniAuth provides the following key features:

• Multi-provider authentication
• Over 200 supported authentication providers (see list at https://github.com/intridea/omniauth/wiki/List-of-Strategies)
• Open source

"SDK's" is the primary reason why developers consider OAuth.io over the competitors, whereas "Easy Social Login" was stated as the key factor in picking OmniAuth.

OmniAuth is an open source tool with 6.88K GitHub stars and 877 GitHub forks. Here's a link to OmniAuth's open source repository on GitHub.
