Thanks for your comment. We believe offering our users more choice is always a good thing. Moreover, while we do provide a similar service, the way we deliver and our goals are slightly different.

Pusher uses WebSockets; this is awesome and a very forward thinking technology however can be limited by older browsers and proxies not supporting the WebSocket connection. Notifyr uses EventSource (also a HTML5 spec) and XMLHttpRequest, aiming to support a majority of browsers, including mobile browsers.

Additionally, we aim to integrate with Apple and Google's push notification system in the future, allowing a universal method for sending push messages with one API for any platform, device or browser.

Pusher actually degrades to Flash Sockets if a browser doesn't support WebSockets: http://pusher.com/docs/flash_fallback

Here's their browser compatibility: http://pusher.com/docs/browser_compatibility

I'm biased - we use Pusher and love it - but regardless, didn't want misinformation spread. :) I'm all for competition.

On what project do you use Pusher? tinfoilsecurity.com ?

[nehz]

Yup no worries :D And Pusher is a fantastic service

More choice is only a good thing when you make it abundantly clear what it is you're going different, and why someone should use you. Otherwise, you're just making it harder for people to make a decision about what tools to use. Your front page doesn't do a very good job at that right now.

The fact that the claim you made here about Pusher and legacy was so quickly disproven, makes things even worse.

Hmm, doesn't Urban Airship integrate with the stores too? At any rate, this looks very well done, congratulations and good luck!

Thanks :)

From what I gather, Urban Airship aims more at providing a service for native apps rather then web based apps, but I could be mistaken.
