Although I haven't used any of the software, I greatly prefer the pagekite website to either localtunnel's or showoff-io's. Thanks for providing a depth of well-organized content. That said, you could benefit from simplifying your quickstart page and featuring it more prominently.
Thanks for the kinds words and the feedback! We got lots of good feedback last time these things were discussed here on HN, hopefully we've made some progress.
Regarding our quick-start, we absolutely agree - except rather than simplify it, we'd prefer to get rid of it altogether by improving the UI of the product itself to the point where it doesn't need so much explaining. That effort is ongoing and should launch later this summer. :-)
