The “real-time web” is a popular topic right now. My WebHooks initiative is both riding on this success and helping make it a reality. One sector of this trend is about notifications. Real-time notifications to you about events you care about.
For a long time we’ve had helper apps like the Google Notifier and more recently the Facebook Desktop Notifications app that bring events from the web to your desktop. Twitter has created a whole ecosystem of clients that not only let you actively check Twitter, but passively get updates from Twitter.
Simultaneously, we’ve had a bunch of systems like Growl emerge that give you a consistent, well-designed and customizable system for local applications to give you notifications. While your IM client is in the background, it can tell you somebody IM’d you and what they said in an unobtrusive way. It integrates with email applications to tell you of new emails. It gives any application developer a nice way to present notifications to the user in a way that’s in their control.
Some of the apps that bring web applications to your desktop like Tweetie, Google Notifier, etc will integrate with Growl (which has a counterpart on pretty much every platform, including the iPhone). The problem is that you only get these notifications when the desktop apps are running, despite the fact web apps are always running. And yes, you have to have an app running for each web application you use.
And that’s only if they built a desktop app and you were convinced to download it. Most web applications are never be able to notify you with any means other than email. But as I’ve argued before, notifications don’t belong in your inbox!
Another minor point is that all these apps use polling to get updates. In some cases this doesn’t matter, but as data starts moving in real-time, this batches your notifications into bursts that you may not be able to parse all at once. I use Tweetie to get Growl notifications from Twitter at the moment, and if a lot of people are updating, I get a huge screen of updates that I don’t have time to read before they disappear. It becomes useless.
A while back I attempted to make an app called Yapper that lets anybody send real-time notifications to your desktop via XMPP. It was an experiment, and ultimately not the answer. It was only part of the solution.
But today I’m announcing the full solution: a free, public, open-source web service called Notify.io (Notify-I-O).
Notify.io integrates with Growl and other local notifiers (as well as email, Jabber, Twitter, and webhooks) and provides a dead-simple API for any web developer to send real-time notifications to their users.
You can think of Notify.io as a web-level Growl system. It empowers users with a consistent, controllable way to get notifications, and it provides developers with a simple, consistent way for sending those notifications.
Notify.io is an open platform for notifications. It’s still in a pre-alpha state, but it already has several useful notification sources. Last Thursday I built Feed Notifier, which uses PubSubHubbub to give you real-time desktop notifications of Atom and RSS feed updates.
At SHDH 35 last Saturday, Abi Raja built a Facebook notification adapter for Notify.io that’s yet to be released. And there a couple more in the pipeline (by me and others) to show the power of Notify.io.
Again, it’s pre-alpha, so before I talk much more about it, I should probably finish more of it. I just wanted to make sure I blogged about it in somewhat of a timely fashion. I seem to have a backlog of blog posts about apps I’ve built recently. However, Notify.io is a pretty significant one. Feel free to check it out, just remember that despite its looks, it’s nowhere near finished — but it does work.
