Amazon SNS vs Notifiers vs OneSignal

In most cases, developers can get started with Amazon SNS by using just three APIs: CreateTopic, Subscribe, and Publish. Additional APIs are available, which provide more advanced functionality.;With SNS you can publish a message once, and deliver it one or more times. So you can choose to direct unique messages to individual Apple, Google or Amazon devices, or broadcast deliveries to many mobile devices with a single publish request.;SNS allows you to group multiple recipients using topics. A topic is an “access point” for allowing recipients to dynamically subscribe for identical copies of the same notification. One topic can support deliveries to multiple endpoint types -- for example, you can group together iOS, Android and SMS recipients. When you publish once to a topic, SNS delivers appropriately formatted copies of your message to each subscriber.;Amazon SNS allows applications and end-users on different devices to receive notifications via Mobile Push notification (Apple, Google and Kindle Fire Devices), HTTP/HTTPS, Email/Email-JSON, SMS or Amazon Simple Queue Service (SQS) queues.;Amazon SNS provides access control mechanisms to ensure that topics and messages are secured against unauthorized access

Spend your precious time on your own code base, instead of chasing down 3rd party provider APIs; A minimal set of well known and stable dependencies (requests, jsonschema and click); A unified interface means that you already support any new providers that will be added, no more work needed!; Thorough testing means protection against any breaking API changes. We make sure your code your notifications will always get delivered!
