PageKite is a hosted TSL (SSL) (Transport Layer Security) service. Or put more simply:
A very easy way to share your local development server with the world.
Previously I had used the following similar services:
- ShowOff - a beautifully packaged service with abysmal support. I had to cancel my account on principal.
- LocalTunnel - free service which works pretty well for the price. I find the lack of a dedicated address very frustrating (not to mention the errant requests to old addresses).
Back to PageKite:
- Pay for only what you use is a nice touch
- SSL support
- Easy setup (at least on OS X)
And my absolute favorite feature: It Just Works.
I have been using it for all of 60 minutes, but so far it appears to be very solid. In addition, the founder of PageKite appears to be dedicated and engaged.
If you need a dedicated ‘tunneling’ service, I would recommend checking out PageKite.
 Bjarni corrected me in the comments that PageKite uses TLS instead of SSH which allows it run in places SSH may not be an option (Windows, Android, etc). It is also available via OSS if you want to run it on your own.
 LocalTunnel is also OSS, so you could host your own instance, but as I have stated before, I have zero desire to actually ever manage a server on my own again.
