XS2 PUSH Notification Platform – a hosted solution

Why a hosted push server solution?

There are enough tutorials on the internet to setup a push server. But as an app developer do you really want to allocate your precious time to this? And how do you know that those tutorials after all that work will provide you with a reliable and scalable solution? Experience is required for writing low-level socket code for communication and also for server security, scalability, data backup, reporting and maintenance.

At XS2 we spent considerable time the last years to build such a platform for our clients. Since we love technology and are Open Source fans we want to open our Service for the world and also for a fair price.

What are the advantages of using the XS2 Push Platform:

• Start quickly. No need to setup a server and design a redundant scalable server architecture.
• Less code, stay focussed on your apps. Write simpler, smaller code for accessing Apple, Google’s and RIM’s Push services using XS2’s simple API.
• Less maintenance. Push notification API’s change regularly, we’ll do the migrating work for you.
• Versatile. Send the push notifications by triggering our API or login into our webinterface to fire them manually.
• Statistics. Check the amount of registered devices and sent push notifications.

Pricing example

• 2,5 million pushes a month, unlimited applications, users and 1 platform: € 19,95 per month
• Extra platform (eg. Android): €5,00 per month

The subscription can be cancelled per month. When you sign up, your first invoice is pro-rated until the end of the month. After that, your subscription is automatically renewed on the first of each month.

Push quotas are soft caps and if you go over by a few thousands we usually won’t invoice. We also send an e-mail when you reach 80% of your monthly quota. If you believe you will need more pushes a month, please contact info@xs2theworld.com for more information.
